Significantly high polarization degree of the very low-albedo asteroid (152679) 1998 KU
Daisuke Kuroda, Masateru Ishiguro, Makoto Watanabe +7
We present a unique and significant polarimetric result regarding the near-Earth asteroid (152679) 1998 KU , which has a very low geometric albedo. From our observatio…
Follow-up observations for the Asteroid Catalog using AKARI Spectroscopic Observations
Sunao Hasegawa, Daisuke Kuroda, Kenshi Yanagisawa +1
In the 1-2.5 micron range, spectroscopic observations are made on the AcuA-spec asteroids, whose spectra were obtained in a continuous covered mode between 2.5-5.0 micron by AKARI.…
Thermal Modeling of Comet-Like Objects from AKARI Observation
Yoonsoo P. Bach, Masateru Ishiguro, Fumihiko Usui
We investigated the physical properties of the comet-like objects 107P/(4015) Wilson--Harrington (4015WH) and P/2006 HR30 (Siding Spring; HR30) by applying a simple thermophysical…
Polarimetric Study of Near-Earth Asteroid (1566) Icarus
Masateru Ishiguro, Daisuke Kuroda, Makoto Watanabe +13
We conducted a polarimetric observation of the fast-rotating near-Earth asteroid (1566) Icarus at large phase (Sun-asteroid-observer's) angles = 57 deg--141deg around the 2015 s…
Organized Autotelescopes for Serendipitous Event Survey (OASES): design and performance
Ko Arimatsu, Kohji Tsumura, Kohei Ichikawa +7
Organized Autotelescopes for Serendipitous Event Survey (OASES) is an optical observation project that aims to detect and investigate stellar occultation events by kilometer-sized…
