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…
Spectroscopic diagnostic of halos and elves detected from space-based photometers
F. J. Pérez-Invernón, A. Luque, F. J. Gordillo-Vázquez +4
In this work, we develop two spectroscopic diagnostic methods to derive the peak reduced electric field in Transient Luminous Events (TLEs) from their optical signals. These method…
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…
Photonuclear Reactions in Lightning Discovered from Detection of Positrons and Neutrons
Teruaki Enoto, Yuuki Wada, Yoshihiro Furuta +9
Lightning and thundercloud are the most dramatic natural particle accelerators on the Earth. Relativistic electrons accelerated by electric fields therein emit bremsstrahlung gamma…
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…
