Second-timescale Glints from Satellites and Space Debris Detected with Tomo-e Gozen
Masaomi Tanaka, Ichiro Takahashi, Naoki Yoshida +17
A search for second-timescale optical transients is one of the frontiers of time-domain astronomy. However, it has been pointed out that reflections of sunlight from Earth-orbiting…
Multicolor Photometry of Tiny Near-Earth Asteroid 2015 RN Across a Wide Range of Phase Angles: Possible Mission Accessible A-type Asteroid
Jin Beniyama, Ryou Ohsawa, Chrysa Avdellidou +10
Studying small near-Earth asteroids is important to understand their dynamical histories and origins as well as to mitigate the damage of the asteroid impact to the Earth. We repor…
Simultaneous Multicolor Photometry of the DESTINY target asteroid (3200) Phaethon
Jin Beniyama, Tomohiko Sekiguchi, Daisuke Kuroda +11
Accurate estimation of brightness of (3200) Phaethon up to lower phase angles are essential for planning of the on-board camera of the DESTINY mission. We have carried out in…
Video Observations of Tiny Near-Earth Objects with Tomo-e Gozen
Jin Beniyama, Shigeyuki Sako, Ryou Ohsawa +20
We report the results of video observations of tiny (diameter less than 100 m) near-Earth objects (NEOs) with Tomo-e Gozen on the Kiso 105 cm Schmidt telescope. A rotational period…
Dippers from TESS Full-frame Images. II. Spectroscopic Characterization of Four Young Dippers
Yui Kasagi, Takayuki Kotani, Hajime Kawahara +9
Photometric monitoring by the Transiting Exoplanet Survey Satellite (TESS) has discovered not only periodic signals by transiting exoplanets but also episodic or quasi-periodic dim…
Dippers from the TESS Full-Frame Images I: The Results of the first 1 year data and Discovery of A Runaway dipper
Tomoyuki Tajiri, Hajime Kawahara, Masataka Aizawa +9
We present a comprehensive catalog of the dippers---young stellar objects that exhibit episodic dimming---derived from the one year's worth of data of Transiting Exoplanet Survey S…
