New evidence supporting past dust ejections from active asteroid (4015) Wilson-Harrington
Sunho Jin, Masateru Ishiguro, Jooyeon Geem +15
Context. (4015) Wilson-Harrington (hereafter, WH) was discovered as a comet in 1949 but has a dynamical property consistent with that of a near-Earth asteroid. Although there is a…
Spectral Type and Geometric Albedo of (98943) 2001 CC21, the Hayabusa2# Mission Target
Jooyeon Geem, Masateru Ishiguro, Mikael Granvik +18
We conducted optical polarimetry and near-infrared spectroscopy of JAXA's Hayabusa2# mission target, (98943) 2001 CC21, in early 2023. Our new observations indicated that this aste…
Polarimetric Properties of the Near--Sun Asteroid (155140) 2005 UD in Comparison with Other Asteroids and Meteoritic Samples
Masateru Ishiguro, Yoonsoo P. Bach, Jooyeon Geem +26
The investigation of asteroids near the Sun is important for understanding the final evolutionary stage of primitive solar system objects. A near-Sun asteroid, (155140) 2005 UD, ha…
A polarimetric study of asteroids in comet-like orbits
Jooyeon Geem, Masateru Ishiguro, Yoonsoo P. Bach +16
Context. Asteroids in comet-like orbits (ACOs) consist of asteroids and dormant comets. Due to their similar appearance, it is challenging to distinguish dormant comets from ACOs v…
