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…
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…
Optical and Near-Infrared Polarimetry of Non-Periodic Comet C/2013 US10 (Catalina)
Y. G. Kwon, M. Ishiguro, D. Kuroda +12
We present an optical and near-infrared (hereafter NIR) polarimetric study of a comet C/2013 US10 (Catalina) observed on UT 2015 December 17-18 at phase angles of =52.1 deg - 53…
New observational evidence of active asteroid P/2010 A2: Slow rotation of the largest fragment
Yoonyoung Kim, Masateru Ishiguro, Myung Gyoon Lee
We report new observations of the active asteroid P/2010 A2 taken when it made its closest approach to the Earth (1.06 au in 2017 January) after its first discovery in 2010. Despit…
Anisotropic Ejection from Active Asteroid P/2010 A2: An Implication of Impact Shattering on an Asteroid
Yoonyoung Kim, Masateru Ishiguro, Tatsuhiro Michikami +1
We revisited a mass ejection phenomenon that occurred in asteroid P/2010 A2 in terms of the dynamical properties of the dust particles and large fragments. We constructed a model a…
