Novel application to estimate the mass-loss and the dust-formation rates in O-type gamma-ray binaries using near-infrared photometry
Yuki Moritani, Akiko Kawachi, Atsuo T. Okazaki +2
We have performed the near-infrared photometric monitoring observations of two TeV gamma-ray binaries with O-stars (LS 5039 and 1FGL J1018.6-5856), using IRSF/SIRIUS at SAAO, in or…

Orbital solution leading to an acceptable interpretation for the enigmatic gamma-ray binary HESS J0632+057
Yuki Moritani, Takafumi Kawano, Sho Chimasu +4
High-dispersion spectroscopic monitoring of HESS J0632+057 has been carried out over four orbital cycles in order to search for orbital modulation, covering the entire orbital phas…

J-GEM Follow-Up Observations of The Gravitational Wave Source GW151226
Michitoshi Yoshida, Yousuke Utsumi, Nozomu Tominaga +35
We report the results of optical--infrared follow-up observations of the gravitational wave (GW) event GW151226 detected by the Advanced LIGO in the framework of J-GEM (Japanese co…
