    Abstract Asymptotic giant branch (AGB) stars are one of the main sources of dust in the Universe. They form and supply dust triggered by stellar pulsations, but the details of the mechanism are still unknown. Among all AGB stars, dusty AGB stars are the most important in terms of dust supply because they contain the star with a high mass-loss rate. To investigate the relationship between the pulsation and the dust supply for such dusty AGB stars, long-term mid-infrared monitoring is necessary. In this study, we combine data from a infrared astronomical satellites AKARI and WISE to generate mid-infrared long-term observation data. This collected data enables us to investigate the variability of dusty AGB stars with a variability period of more than several hundred days (>250 d). Furthermore, we determine the mid-infrared variability amplitudes of 169 O-rich AGB stars and 28 OH/IR stars in our Galaxy, as well as data at other wavelengths. This study is the largest study on mid-infrared variability. Additionally, we discover a positive correlation between the variability amplitude A18μm in the 18μm band and the $\mathit {W3}-\mathit {W4}$ infrared color which is the measure of the dust supply. Also, we find that this relationship is independent of the variability period and mode. Finally, we calculate the radiative transfer of circumstellar dust from AGB stars. The result of our calculations showed that $A_{18\mu \rm {m } }$ is strongly affected by the luminosity change ratio of the central star. These experimental results imply that the luminosity change ratio has a strong influence on the dust supply of AGB star.

    Abstract A near-infrared telescope with an effective aperture diameter of 30 mm has been developed. The primary objective of the development is to observe northern bright stars in the J, H, and Ks bands and provide accurate photometric data on those stars. The second objective is to observe a belt-like region along the northern Galactic plane (|b| ≤ 5° and δ ≥ −30°) repeatedly, to monitor bright variable stars there. The telescope has been in use since 2016 December. The purpose of this paper is to describe the design and operational performances of the telescope, the photometric calibration methods, and our scientific goals. We show that the telescope has the ability to provide photometry with an uncertainty of less than $5\%$ for stars brighter than 7, 6.5, and 6 mag in the J, H, and Ks bands, respectively. The repeatability of the photometric measurements for the same star is better than $1\%$ for bright stars. Our observations will provide accurate photometry on bright stars that are lacking in the Two Micron Sky Survey and the Two Micron All-Sky Survey. Repeated observations at a good cadence will also reveal their nature in terms of variability in the near-infrared.

    <title>Abstract</title> Metal-deficient stars are important tracers for understanding the early formation of the Galaxy. Recent large-scale surveys with both photometric and spectroscopic data have reported an increasing number of metal-deficient stars whose kinematic features are consistent with those of the disk stellar populations. We report the discovery of an RR Lyrae variable (hereafter RRL) that is located within the thick disk and has an orbit consistent with the thick-disk kinematics. Our target RRL (HD 331986) is located at around 1 kpc from the Sun and, with <italic>V</italic> ≃ 11.3, is among the ∼130 brightest RRLs known so far. However, this object has scarcely been studied because it is in the midplane of the Galaxy, at a Galactic latitude around –1°. Its near-infrared spectrum (0.91–1.32 <italic>μ</italic>m) shows no absorption line except hydrogen lines of the Paschen series, suggesting [Fe/H] ≲ –2.5. It is the most metal-deficient RRL, at least among RRLs whose orbits are consistent with the disk kinematics, although we cannot determine to which of the disk and the halo it belongs. This unique RRL would provide us with essential clues for studying the early formation of stars in the inner Galaxy with further investigations, including high-resolution optical spectroscopy.

    Radar and optical simultaneous observations of meteors are important to understand the size distribution of the interplanetary dust. However, faint meteors detected by high power large aperture radar observations, which are typically as faint as 10 mag. in optical, have not been detected until recently in optical observations, mainly due to insufficient sensitivity of the optical observations. In this paper, two radar and optical simultaneous observations were organized. The first observation was carried out in 2009 to 2010 using Middle and Upper Atmosphere Radar (MU radar) and an image-intensified CCD camera. The second observation was carried out in 2018 using the MU radar and a mosaic CMOS camera, Tomo-e Gozen, mounted on the 1.05-m Kiso Schmidt Telescope. In total, 331 simultaneous meteors were detected. The relationship between radar cross sections and optical V-band magnitudes was well approximated by a linear function. A transformation function from the radar cross section to the V-band magnitude was derived for sporadic meteors. The transformation function was applied to about 150,000 meteors detected by the MU radar in 2009--2015, large part of which are sporadic, and a luminosity function was derived in the magnitude range of $-1.5$ to $9.5$ mag. The luminosity function was well approximated by a single power-law function with the population index of $r = 3.52{\pm}0.12$. The present observation indicates that the MU radar has capability to detect interplanetary dust of $10^{-5}$ to $10^{0}$ g in mass as meteors.

    <jats:title>Abstract</jats:title> <jats:p>Using a prototype of the Tomo-e Gozen wide-field CMOS mosaic camera, we acquire wide-field optical images at a cadence of $2\:$Hz and search them for transient sources of duration 1.5 to $11.5\:$s. Over the course of eight nights, our survey encompasses the equivalent of roughly two days on one square degree, to a fluence equivalent to a limiting magnitude of about $V = 15.6$ in a 1-s exposure. After examining by-eye the candidates identified by a software pipeline, we find no sources which meet all our criteria. We compute upper limits to the rate of optical transients consistent with our survey, and compare those to the rates expected and observed for representative sources of ephemeral optical light.</jats:p>

    We have developed a near-infrared camera called ANIR (Atacama Near-InfraRed camera) for the University of Tokyo Atacama Observatory 1.0m telescope (miniTAO) installed at the summit of Cerro Chajnantor (5640 m above sea level) in northern Chile. The camera provides a field of view of 5'.1 $\times$ 5'.1 with a spatial resolution of 0".298 /pixel in the wavelength range of 0.95 to 2.4 $\mu$m. Taking advantage of the dry site, the camera is capable of hydrogen Paschen-$\alpha$ (Pa$\alpha$, $\lambda=$1.8751 $\mu$m in air) narrow-band imaging observations, at which wavelength ground-based observations have been quite difficult due to deep atmospheric absorption mainly from water vapor. We have been successfully obtaining Pa$\alpha$ images of Galactic objects and nearby galaxies since the first-light observation in 2009 with ANIR. The throughputs at the narrow-band filters ($N1875$, $N191$) including the atmospheric absorption show larger dispersion (~10%) than those at broad-band filters (a few %), indicating that they are affected by temporal fluctuations in Precipitable Water Vapor (PWV) above the site. We evaluate the PWV content via the atmospheric transmittance at the narrow-band filters, and derive that the median and the dispersion of the distribution of the PWV are 0.40+/-0.30 mm for $N1875$ and 0.37+/-0.21 mm for $N191$, which are remarkably smaller (49+/-38% for $N1875$ and 59+/-26% for $N191$) than radiometry measurements at the base of Cerro Chajnantor (5100 m alt.). The decrease in PWV can be explained by the altitude of the site when we assume that the vertical distribution of the water vapor is approximated at an exponential profile with scale heights within 0.3-1.9 km (previously observed values at night). We thus conclude that miniTAO/ANIR at the summit of Cerro Chajnantor indeed provides us an excellent capability for a "ground-based" Pa$\alpha$ observation.

    Luminous infrared galaxies (LIRGs) are enshrouded by a large amount of dust, produced by their active star formation, and it is difficult to measure their activity in the optical wavelength. We have carried out Pa$\alpha$ narrow-band imaging observations of 38 nearby star-forming galaxies including 33 LIRGs listed in $IRAS$ RBGS catalog with the Atacama Near InfraRed camera (ANIR) on the University of Tokyo Atacama Observatory (TAO) 1.0 m telescope (miniTAO). Star formation rates (SFRs) estimated from the Pa$\alpha$ fluxes, corrected for dust extinction using the Balmer Decrement Method (typically $A_V$ $\sim$ 4.3 mag), show a good correlation with those from the bolometric infrared luminosity of $IRAS$ data within a scatter of 0.27 dex. This suggests that the correction of dust extinction for Pa$\alpha$ flux is sufficient in our sample. We measure the physical sizes and the surface density of infrared luminosities ($\Sigma_{L(\mathrm{IR})}$) and $SFR$ ($\Sigma_{SFR}$) of star-forming region for individual galaxies, and find that most of the galaxies follow a sequence of local ultra luminous or luminous infrared galaxies (U/LIRGs) on the $L(\mathrm{IR})$-$\Sigma_{L(\mathrm{IR})}$ and $SFR$-$\Sigma_{SFR}$ plane. We confirm that a transition of the sequence from normal galaxies to U/LIRGs is seen at $L(\mathrm{IR})=8\times10^{10}$ $L_{\odot}$. Also, we find that there is a large scatter in physical size, different from those of normal galaxies or ULIRGs. Considering the fact that most of U/LIRGs are merging or interacting galaxies, this scatter may be caused by strong external factors or differences of their merging stage.

    We studied the period-K magnitude (P-K) relations of nearby Mira and Mira-like variables with relatively good Hipparcos parallaxes. They form at least two prominent sequences on the P-K plane, corresponding to the sequences C (Mira variables pulsating in the fundamental mode) and C'(Mira variables pulsating in the 1st overtone mode), that were found in the LMC. As a part of an ongoing study to see the differences between the Mira variables pulsating in the fundamental and the 1st overtone mode, we searched for SiO masers in the nearby variables on the sequences C' and C using the Nobeyama 45m radio telescope. We observed 28 selected nearby Mira and Mira-like variables without previous maser observations, and found 3 new emitters. The observational result shows that there is few or no SiO maser emitters pulsating in the 1st overtone mode.

    SPICA Science Conference from Exoplanets to Distant Galaxies: SPICA's New Window on the Cool Universe (June 18-21, 2013. Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, JapanWe present a result of high-resolution 30 μm imaging observations of the Homunculus Nebula of Eta Carinae (η Car). The Homunculus Nebula is known to contain a large amount of cool dust (approximately 100 K) at polar lobes and a equatorial torus. While the distribution of the cool dust shows the past dust formation events on Car such as giant eruptions and binary interactions, no spatially resolved images at long mid-infrared wavelengths (30-50 μm) have been obtained. We observed Car with a mid-infrared camera MAX38 on the University of Tokyo Atacama 1.0-m telescope, and successfully obtained spatially resolved images of the Homunculus Nebula at 18.7, 31.7 and 37.3 μm. The observations revealed the structure of the massive equatorial torus which contains the dust of 0.09 solar mass. This amount is equal to approximately 80% of the total dust mass 0.12 solar mass in the Homunculus Nebula. It is also found that the dust of 0.012 solar mass exists inside the polar lobes. Assuming that the dust was constantly formed after the giant eruption occurred in 1843, the dust formation rate is estimated as 7 × 10(exp -5)solar mass yr(exp -1). This indicates that the binary interaction plays a significant role in the dust formation on Car.Number of authors: 29Physical characteristics: Original contains color illustrations

    Hayabusa 2 is an asteroid sample return mission following Hayabusa mission. This mission is now under study and mission target is c-type asteroid 1999JU3. From summer 2007 to April 2008 the observation from the earth is favorable conditions. This chance of observation is the first in 8 years from discovery. About 1999JU3 we had known only spectral type until now so we had observed lightcurve of it in July 2007. As a result we have found that its rotational period is about under 6 hours. This time, we will report about information of 1999JU3 we had get until now for example the result of lightcurve from July to September and about the result of AKARI in May and so on.

    As a result of increasing the size of telescopes and the sensitivity of observational instruments, it has become difficult to observe bright stars due to saturation problems. Bright stars should be the most important objects to study because they are easy to observe in detail (e.g., high-dispersion spectroscopy, which requires more photons), and they can be observed at wavelengths such as ultraviolet, infrared, and radio, where the sensitivity of observational instruments is not good. However, for bright stars, their infrared brightness, which should be the most fundamental data, had not been determined with high accuracy. Therefore, we developed a small aperture telescope dedicated to observing bright stars in infrared. We used this telescope to determine the infrared brightness of the bright stars with unprecedented accuracy, and to monitor the temporal variation of the brightness.

    The Linear Variable Filter (LVF) designed for observation of atmospheric emission in Antarctica has been fabricated. The spectral transmission of the delivered LVF was good, and we expect to obtain the atmospheric spectrum in the K-dark band if the observation in Antarctica can be realized. Maintenance of the refrigerator for the infrared detector has been carried out, and astronomical observations have been continued in Okayama. We gave a poster presentation on this research plan at the international conference Polar2018, and we also visited the University of Nice in France to discuss the feasibility of the observation at the Dome C in Antarctica. However, we were not able to obtain a concrete plan for the realization of the observations with our equipments in Antarctica.

    We successfully completed a wide-field CMOS-sensor optical imaging instrument, Tomo-e Gozen, for the 1.05-m Kiso Schmidt telescope in April 2019. The field-of-view of the instrument is 20 square degrees. We also developed an algorithm to efficiently survey a large area of the sky and a dedicated data reduction system for a large dataset obtained with Tomo-e Gozen (several TBs per night). We have started a systematic wide-field high-cadence transient survey since November 2019 and changed the observing strategy so that we would take 30-minute-cadence data. We successfully got a good-quality data for very early-phase data of transients.

    本年度は昨年度に引き続き南アフリカ天文台・サザーランド観測所の IRSF望遠鏡や岡山天体物理観測所に設置されている赤外線望遠鏡IR-TMTを用いて天の川銀河の銀河面や大小マゼラン雲に存在するWolf-Rayet星のモニター観測を行った。観測の目的は、食による減光の有無を調べ、Wolf-Rayet星の近接連星の割合を調べ、Wolf-Rayet星を形成するために必要な質量損失を引き起こす主要因が近接連星系の中の質量のはぎ取りであるかどうかを検証することである。例年にない悪天候や装置のトラブルが発生したために、取得できたデータの量が当初の想定を下回った。そのため昨年度に取得したデータを含めて一通りデータ解析を行ったが、2年間の研究期間では統計的に有意な結果を得られるサンプル数を集めることはできなかった。しかしながら、今後順調にデータを取得することができれば、1-2年程度で定量的な制限をつけることができるようになると期待される。 <BR> また、長期間サザーランド観測所に滞在したことにより、南アフリカ共和国の天文学者を含めた共同研究に発展し、滞在中に観測を担当するなどして、1本の共著の論文が出版された。さらに、銀河面や大小マゼラン雲といった恒星の多い領域を観測していたこともあり、副産物としてこれらの中にあるレッドクランプ星のデータも得ることができた。レッドクランプ星は天体まで距離を測るために使われる標準光源と呼ばれる天体の一つであり、その光度を正確に測定することは正確に距離を知ることにつながり、天文学のさまざまな基本的な量を知る上で非常に重要である。今回得られたデータにより、レッドクランプ星の光度の金属量や年齢への依存性、絶対値の情報が得られている。これらの結果は天文学会の年会等の研究会で発表した他、共同研究者の間で論文のドラフトを回覧中であり、近いうちに投稿予定である。

    We have developed the optical and near-infrared spectrometer for the spectroscopic observation of Mira variable stars, whose pulsation mechanism is not understood well. This spectrometer covers the wavelength range from 0.45um to 2.5um with a resolution R of a few hundreds. We have confirmed that the spectrometer has the expected optical performance in the room temperature. We also cooled down the spectrometer to the operating temperature, and examined the optical performance. However, the focal plane array was broken during the low temperature experiment, and it became impossible to proceed this research as we planed. We have continued the optical adjustment at the operating temperature using the InGaAs detector array. Unfortunately, we have not achieved the good optical performance yet.

    Small astronomical and site-test instruments were deployed at the Dome Fuji station of National Institute of Polar Research to study the astronomical environment. The Dome Fuji station was found to be the best site for the studies of the exoplanet atmosphere and for wide field surveys of galaxies in the early universe with infrared telescopes and cameras. The technical and engineering problems to construct mid-size infrared telescope on snow in low temperature of -80 Celsius at inland Antarctica and a multi-object infrared spectrograph dedicated to the study of exoplanet atmosphere were studied. Then a 2.5m infrared telescope and a 3-color infrared camera were designed.

    This research aims to make systematic observations in the infrared region for the Large Magellanic Cloud and nearby galaxies with AKARI, which was launched in 2006 February, and construct a fundamental database from the near-to far-infrared region as well as a point source catalog of the Large Magellanic cloud. Together with these AKARI data, complementary spectroscopic observations with Spitzer of star-forming regions and nearby galaxies were carried out to study material evolution and circulation in galaxies based on systematic observations of the interstellar matter in the various physical conditions.

    【目的】自然科学に興味のある高校生に、天文学者が行っている研究を体験してもらい、将来の進路選択の幅を広げてもらう。 【講義】大学院生による、自分の経験に基づく進路選択および研究の進め方、研究と勉強の違いについての講義と、教員による最先端の研究紹介、および研究を進めるために必要な観測天文学の基礎を学ぶ。 【実験・実習】4名程度の受講生からなる研究チームを編成し、実験及び観測はそれぞれの研究チーム毎に異なるテーマで行う。毎日各チームの研究の進捗発表会を行い、チーム間で質問・コメント・批判を行う時間を持つ。 ・何の為にどのような観測を行うのか、その研究に宇宙望遠鏡による赤外線データをどう用いるのか研究提案書を受講生が自らの考えを基に作成し、それを研究者が評価を行う。 ・データの科学的な解析を行い、結果についての考察を行う。 ・高校生の研究成果を専門家や一般市民の前でプレゼンテーションを行い、研究についてのフィードバックをもらう。 【実施場所】本学天文学専攻・仙台市天文台及びせんだいメディアテークで実施される。 一連の実験及び実習は、高校生と年齢の近い大学生及び大学院生がサポートするが、研究テーマを高校生自らが設定し、手順を自分たちで考え、結果に自分たちでたどり着くようサポートに徹し、高校生が主体となって研究を行っていることを実感できるように配慮する。
