Inversion angle of phase-polarization curve of near-Earth asteroid (3200) Phaethon
Yoshiharu Shinnaka, Toshihiro Kasuga, Reiko Furusho +5
The linear polarization degree (referred to the scattering plane, P_r) as a function of the solar phase angle, α, of solar system objects is a good diagnostic to understand the sca…
Photometric Measurements of H2O Ice Crystallinity on Trans-Neptunian Objects
Tsuyoshi Terai, Yoichi Itoh, Yumiko Oasa +2
We present a measurement of H2O ice crystallinity on the surface of trans-neptunian objects (TNOs) with near-infrared narrow-band imaging. The newly developed photometric technique…
Initial Speed of Knots in the Plasma Tail of C/2013 R1(Lovejoy)
Masafumi Yagi, Jin Koda, Reiko Furusho +3
We report short-time variations in the plasma tail of C/2013 R1(Lovejoy). A series of short (two to three minutes) exposure images with the 8.2-m Subaru telescope shows faint detai…
Detection of parent H2O and CO2 molecules in the 2.5--5 micron spectrum of comet C/2007 N3 (Lulin) observed with AKARI
Takafumi Ootsubo, Fumihiko Usui, Hideyo Kawakita +13
Comet C/2007 N3 (Lulin) was observed with the Japanese infrared satellite AKARI in the near-infrared at a post-perihelion heliocentric distance of 1.7 AU. Observations were perform…
