Spectrophotometric accuracy of spectra obtained from spectroscopic plates measured with a commercial flatbed scanner
Kenshi Yanagisawa, Reiko Furusho, Shiomi Nemoto +3
The intensity spectra recovered from the spectroscopic photographic plates were compared with the CCD spectra, and we found the difference between the two was 2.5%.The measurements…

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…
