A calibrated dust-trail model of the Leonid meteoroid stream and forecasts of the 2031-2035 encounters
Shinsuke Abe
We combine N-body dust-trail generation with a fast nodal-encounter forecast and apply the model to the Leonid returns of 2031-2035. The dominant error is neither the ejection phys…
Rotational effect as the possible cause of the east-west asymmetric crater rims on Ryugu observed by LIDAR data
Naoyuki Hirata, Noriyuki Namiki, Fumi Yoshida +13
Asteroid 162173 Ryugu is a rubble-pile asteroid, whose top-shape is compatible with models of deformation by spin up. Rims of major craters on Ryugu have an east-west asymmetric pr…
Relationship between Radar Cross Section and Optical Magnitude based on Radar and Optical Simultaneous Observations of Faint Meteors
Ryou Ohsawa, Akira Hirota, Kohei Morita +40
Radar and optical simultaneous observations of meteors are important to understand the size distribution of the interplanetary dust. However, faint meteors detected by high power l…
Rotationally time-resolved vis-spectroscopy of (3200) Phaethon
Daisuke Kinoshita, Katsuhito Ohtsuka, Takashi Ito +4
Apollo-type NEA (3200) Phaethon, classified at the B/F-type taxonomy, probably the main mass of the Phaethon-Geminid stream complex (PGC), can be the most metamorphic C-complex ast…
Plasma distribution of Comet ISON (C/2012 S1) observed using the radio scintillation method
Tomoya Iju, Shinsuke Abe, Munetoshi Tokumaru +1
We report the electron density in a plasma tail of Comet ISON (C/2012 S1) derived from interplanetary scintillation (IPS) observations during November 1--28, 2013. Comet ISON showe…
Optical Properties of (162173) 1999 JU3: In Preparation for the JAXA Hayabusa 2 Sample Return Mission
Masateru Ishiguro, Daisuke Kuroda, Sunao Hasegawa +31
We investigated the magnitude-phase relation of (162173) 1999 JU3, a target asteroid for the JAXA Hayabusa 2 sample return mission. We initially employed the international Astronom…
