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…
Cloud reflection modelling for impact flashes on Jupiter: A new constraint on the bulk properties of the impact objects
Ko Arimatsu, Kohji Tsumura, Fumihiko Usui +1
We investigate optical characteristics of flashes caused by impacting meter- to decameter-sized outer solar system objects on Jupiter and contributions of reflected light from surf…
JASMINE: Near-Infrared Astrometry and Time Series Photometry Science
Daisuke Kawata, Hajime Kawahara, Naoteru Gouda +86
Japan Astrometry Satellite Mission for INfrared Exploration (JASMINE) is a planned M-class science space mission by the Institute of Space and Astronautical Science, the Japan Aero…
Modelling the optical energy profile of the 2021 October Jupiter impact flash
Ko Arimatsu, Kohji Tsumura, Fumihiko Usui +1
We have conducted numerical simulations to reproduce the observed optical energy profile of the 15 October 2021 (UT) impact flash on Jupiter, which was the largest and the most wel…
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…
Detection of an extremely large impact flash on Jupiter by high-cadence multiwavelength observations
Ko Arimatsu, Kohji Tsumura, Fumihiko Usui +1
We report the detection of an optical impact flash on Jupiter on 15 October 2021 by a dedicated telescope, Planetary ObservatioN Camera for Optical Transient Surveys (PONCOTS), for…
