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…
Implications of High Polarization Degree for the Surface State of Ryugu
Daisuke Kuroda, Jooyeon Geem, Hiroshi Akitaya +19
The asteroid exploration project "Hayabusa2" has successfully returned samples from the asteroid (162173) Ryugu. In this study, we measured the linear polarization degrees of Ryugu…
High-Resolution Near-Infrared Polarimetry and Sub-Millimeter Imaging of FS Tau A: Possible Streamers in Misaligned Circumbinary Disk System
Yi Yang, Eiji Akiyama, Thayne Currie +56
We analyzed the young (2.8-Myr-old) binary system FS Tau A using near-infrared (H-band) high-contrast polarimetry data from Subaru/HiCIAO and sub-millimeter CO (J=2-1) line emissio…
SUBARU Near-Infrared Imaging Polarimetry of Misaligned Disks Around The SR24 Hierarchical Triple System
Satoshi Mayama, Sebastián Pérez, Nobuhiko Kusakabe +65
The SR24 multi-star system hosts both circumprimary and circumsecondary disks, which are strongly misaligned from each other. The circumsecondary disk is circumbinary in nature. In…
Polarimetric and Photometric Observations of NEAs; (422699) 2000 PD3 and (3200) Phaethon with the 1.6m Pirka Telescope
Ryo Okazaki, Tomohiko Sekiguchi, Masateru Ishiguro +6
We report on optical polarimetric observations of two Apollo type near-Earth asteroids, (422699) 2000 PD3 and (3200) Phaethon, and BVRI photometric observations of 2000 PD3 using t…
Near-Infrared Imaging Polarimetry toward M17 SWex
Koji Sugitani, Fumitaka Nakamura, Tomomi Shimoikura +7
We conducted near-infrared (JHKs) imaging polarimetry toward the infrared dark cloud (IRDC) M17 SWex, including almost all of the IRDC filaments as well as its outskirts, with the…
