Dust from Comet 209P/LINEAR during its 2014 Return: Parent Body of a New Meteor Shower, the May Camelopardalids
Masateru Ishiguro, Daisuke Kuroda, Hidekazu Hanayama +29
We report a new observation of the Jupiter-family comet 209P/LINEAR during its 2014 return. The comet is recognized as a dust source of a new meteor shower, the May Camelopardalids…
A Long-period Eccentric Substellar Companion to the Evovled Intermediate-Mass Star HD 14067
Liang Wang, Bunei Sato, Masashi Omiya +14
We report the detection of a substellar companion orbiting an evolved intermediate-mass () star HD 14067 (G9 III) using precise Doppler technique. Radial velo…
Multi-band, Multi-epoch Observations of the Transiting Warm Jupiter WASP-80b
Akihiko Fukui, Yui Kawashima, Masahiro Ikoma +22
WASP-80b is a warm Jupiter transiting a bright late-K/early-M dwarf, providing a good opportunity to extend the atmospheric study of hot Jupiters toward the lower temperature regim…
Optical and Near-Infrared Polarimetry of Highly Reddened Type Ia Supernova 2014J: Peculiar Properties of Dust in M82
K. S. Kawabata, H. Akitaya, M. Yamanaka +46
We presented optical and near-infrared multi-band linear polarimetry of the highly reddened Type Ia SN~2014J appeared in M82. SN~2014J exhibits large polarization at shorter wavele…
High-z gamma-ray bursts for unraveling the dark ages mission HiZ-GUNDAM
Daisuke Yonetoku, Tatehiro Mihara, Tatsuya Sawano +28
We are now investigating and studying a small satellite mission HiZ-GUNDAM for future observation of gamma-ray bursts (GRBs). The mission concept is to probe "the end of dark ages…
Variable optical polarization during high state in gamma-ray loud narrow line Seyfert 1 galaxy 1H 0323+342
Ryosuke Itoh, Yasuyuki T. Tanaka, Hiroshi Akitaya +34
We present results of optical polarimetric and multi-band photometric observations for gamma-ray loud narrow-line Seyfert 1 galaxy 1H 0323+342. This object has been monitored by 1.…
