Size, atmospheric, and ring constraints on the large Kuiper belt object (55565) Aya from a stellar occultation
Ko Arimatsu, Hidekazu Hanayama, Satoshi Takita +3
We aim to constrain the projected size, geometric albedo, possible atmosphere, and possible ring material of the mid-sized trans-Neptunian object (55565) Aya from the stellar occul…
Bright Metal-Poor Star Survey - I. Tomo-e Gozen narrow-band photometric survey and medium-resolution spectroscopic follow-up
Hiroko Okada, Takumi Iwasaki, Nozomu Tominaga +21
We present the Tomo-e Gozen Bright Metal-Poor Star Survey (TeMPS), a wide-area narrow-band photometric survey for bright metal-poor stars in the northern sky. The survey uses the T…
Simultaneous Tricolor Video Observations of Three Tiny Near-Earth Asteroids with Sub-Minute Rotation Periods
Jin Beniyama, Ryou Ohsawa, Shigeyuki Sako +4
Studying the physical properties of near-Earth asteroids (NEAs) is crucial for understanding their dynamical histories and origins, and assessing impact hazards to Earth. Tiny NEAs…
The first detection of an atmosphere on a trans-Neptunian object beyond Pluto
Ko Arimatsu, Fumi Yoshida, Tsutomu Hayamizu +4
Trans-Neptunian objects (TNOs) in the outer Solar System are predominantly small, icy worlds long presumed to be atmosphereless except for the largest bodies. Until now, Pluto has…
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…
