Simultaneous Multicolor Photometry of the DESTINY target asteroid (3200) Phaethon
Jin Beniyama, Tomohiko Sekiguchi, Daisuke Kuroda +11
Accurate estimation of brightness of (3200) Phaethon up to lower phase angles are essential for planning of the on-board camera of the DESTINY mission. We have carried out in…
Asymmetry in the number of L4 and L5 Jupiter Trojans driven by jumping Jupiter
Jian Li, Zhihong Jeff Xia, Fumi Yoshida +2
Context. More than 10000 Jupiter Trojans have been detected so far. They are moving around the L4 and L5 triangular Lagrangian points of the Sun-Jupiter system and their distributi…
(3200) Phaethon Polarimetry in the Negative Branch: New Evidence for the Anhydrous Nature of the DESTINY+ Target Asteroid
Jooyeon Geem, Masateru Ishiguro, Jun Takahashi +23
We report on the first polarimetric study of (3200) Phaethon, the target of JAXA's DESTINY mission, in the negative branch to ensure its anhydrous nature and to derive an accur…
Effect of projectile shape and interior structure on crater size in strength regime
T. Kadono, M. Arakawa, S. Tsujido +9
Experiments on crater formation in the strength regime were conducted using projectiles of various shapes with an aspect ratio of ~1, including both solid and hollow interiors. The…
Video Observations of Tiny Near-Earth Objects with Tomo-e Gozen
Jin Beniyama, Shigeyuki Sako, Ryou Ohsawa +20
We report the results of video observations of tiny (diameter less than 100 m) near-Earth objects (NEOs) with Tomo-e Gozen on the Kiso 105 cm Schmidt telescope. A rotational period…
A global system of furrows on Ganymede indicative of their creation in a single impact event
Naoyuki Hirata, Ryo Suetsugu, Keiji Ohtsuki
Furrows are a concentric system of tectonic troughs, and are the oldest recognizable surface feature on Ganymede. We analyzed the distribution of furrows utilizing Voyager and Gali…
Electrostatic Dust Ejection From Asteroid (3200) Phaethon With the Aid of Mobile Alkali Ions at Perihelion
Hiroshi Kimura, Katsuhito Ohtsuka, Shota Kikuchi +12
The asteroid (3200) Phaethon is known to be the parent body of the Geminids, although meteor showers are commonly associated with the activity of periodic comets. What is most pecu…
Size Distribution of Small Jupiter Trojans in the L5 Swarm
Kotomi Uehata, Tsuyoshi Terai, Keiji Ohtsuki +1
We present an analysis of survey observations of the trailing L5 Jupiter Trojan swarm using the wide-field Hyper Suprime-Cam CCD camera on the 8.2 m Subaru Telescope. We detected 1…
Investigating the stability of mass transfer in neutron star-helium white dwarf binaries
Hai-Liang Chen, Thomas M. Tauris, Xuefei Chen +1
Neutron star-helium white dwarf (NS+He WD) binaries are important evolutionary products of close-orbit binary star systems. They are often observed as millisecond pulsars and may c…
Refinement of the convex shape model and tumbling spin state of (99942) Apophis using the 2020-2021 apparition data
H. -J. Lee, M. -J. Kim, A. Marciniak +30
Context. The close approach of the near-Earth asteroid (99942) Apophis to Earth in 2029 will provide a unique opportunity to examine how the physical properties of the asteroid cou…
