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…
Disruption of Saturn's ring particles by thermal stress
Naoyuki Hirata, Ryuji Morishima, Keiji Ohtsuki +1
Spacecraft and ground-based observations show that the main rings of Saturn lack particles larger than 10 m. Tidal or collisional destruction of satellites/comets have been propose…
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…
FOSSIL: I. The Spin Rate Limit of Jupiter Trojans
Chan-Kao Chang, Ying-Tung Chen, Wesley C. Fraser +25
Rotation periods of 53 small (diameters km) Jupiter Trojans (JTs) were derived using the high-cadence light curves obtained by the FOSSIL phase I survey, a Subaru/Hype…
Colors of Centaurs observed by the Subaru/Hyper Suprime-Cam and implications for their origin
Haruka Sakugawa, Tsuyoshi Terai, Keiji Ohtsuki +4
Centaurs have orbits between Jupiter and Neptune and are thought to originate from the trans-Neptunian region. Observations of surface properties of Centaurs and comparison with th…
