Comet 9P/Tempel 1: Interpretation with the Deep Impact Results
Satoru Yamamoto, Hiroshi Kimura, Evgenij Zubko +4
According to our common understandings, the original surface of a short-period comet nucleus has been lost by sublimation processes during its close approaches to the Sun. Sublimat…
Two different evolutionary types of comets proved by polarimetric and infrared properties of their dust
L. Kolokolova, H. Kimura, N. Kiselev +1
Comets can be divided into two groups: type I, characterized by high gas/dust ratio, low polarization, and a weak or absent 10 micron silicate feature, and type II, for which a low…
First Two-Micron Imaging Polarimetry of Beta Pictoris
Motohide Tamura, Misato Fukagawa, Hiroshi Kimura +3
High-resolution K band imaging polarimetry of the beta Pic dust disk has been conducted with adaptive optics and a coronagraph using the Subaru 8.2-m telescope. Polarization of ~10…
Near-Infrared Photometric Monitoring of a Pre-Main-Sequence Object KH 15D
Nobuhiko Kusakabe, Motohide Tamura, Yasushi Nakajima +12
An extensive photometric monitoring of KH 15D, an enigmatic variable in the young star cluster NGC 2264, has been conducted. Simultaneous and accurate near-infrared (JHKs-bands) ph…
