Diffraction modelling of a 2023 March 5 stellar occultation by subkilometer-sized asteroid (98943) 2001 CC21
Ko Arimatsu, Fumi Yoshida, Tsutomu Hayamizu +31
We present an analysis of a stellar occultation event caused by a near-Earth asteroid (98943) 2001 CC21, an upcoming flyby target in the Hayabusa2 extended mission, on March 5, 202…
Quantitative grain size estimation on airless bodies from the negative polarization branch. I. Insights from experiments and lunar observations
Yoonsoo P. Bach, Masateru Ishiguro, Jun Takahashi +4
This work explores characteristics of the negative polarization branch (NPB), which occurs in scattered light from rough surfaces, with particular focus on the effects of fine part…
Quantitative grain size estimation on airless bodies from the negative polarization branch. II. Dawn mission targets (4) Vesta and (1) Ceres
Yoonsoo P. Bach, Masateru Ishiguro, Jun Takahashi +4
Context. Sunlight scattered from the surface of an airless body is generally partially polarized, and the corresponding polarization state includes information about the scattering…
Polarized Transmission Spectrum of Earth as Observed during a Lunar Eclipse
Jun Takahashi, Yoichi Itoh, Kensuke Hosoya +2
Polarization during a lunar eclipse is a forgotten mystery. Coyne & Pellicori (1970) reported the detection of significant polarization during the lunar eclipse on 1968 April 13. M…
