Physical properties of near-Earth asteroids with a low delta-: Survey of target candidates for the Hayabusa2 mission
Sunao Hasegawa, Daisuke Kuroda, Kohei Kitazato +40
Sample return from the near-Earth asteroid known as 25143 Itokawa was conducted as part of the Hayabusa mission, with a large number of scientific findings being derived from the r…
Five New Exoplanets Orbiting Three Metal-Rich, Massive Stars: Two-Planet Systems Including Long-Period Planets, and an Eccentric Planet
Hiroki Harakawa, Bun'ei Sato, Masashi Omiya +13
We report detections of new exoplanets from a radial velocity (RV) survey of metal-rich FGK stars by using three telescopes. By optimizing our RV analysis method to long time-basel…
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…
Lightcurve Survey of V-type Asteroids in the Inner Asteroid Belt
Sunao Hasegawa, Seidai Miyasaka, Hiroyuki Mito +17
We have observed the lightcurves of 13 V-type asteroids ((1933) Tinchen, (2011) Veteraniya, (2508) Alupka, (3657) Ermolova, (3900) Knezevic, (4005) Dyagilev, (4383) Suruga, (4434)…
Optical-to-Near-Infrared Simultaneous Observations for the Hot Uranus GJ3470b: A Hint for Cloud-free Atmosphere
Akihiko Fukui, Norio Narita, Kenji Kurosaki +15
We present optical (g', R_c, and I_c) to near-infrared (J) simultaneous photometric observations for a primary transit of GJ3470b, a Uranus-mass transiting planet around a nearby M…
Photometric Observations of 107P/Wilson-Harrington
Seitaro Urakawa, Shin-ichiro Okumura, Kota Nishiyama +14
We present lightcurve observations and multiband photometry for 107P/Wilson-Harrington using five small- and medium-sized telescopes. The lightcurve has shown a periodicity of 0.29…
Thermo-physical properties of 162173 (1999 JU3), a potential flyby and rendezvous target for interplanetary missions
T. G. Mueller, J. Durech, S. Hasegawa +15
Near-Earth asteroid 162173 (1999 JU3) is a potential flyby and rendezvous target for interplanetary missions because of its easy to reach orbit. The physical and thermal properties…
Optical and Near-Infrared Photometric Observation during the Superoutburst of the WZ Sge-Type Dwarf Nova, V455 Andromedae
R. Matsui, M. Uemura, A. Arai +17
We report on optical and infrared photometric observations of a WZ Sge-type dwarf nova, V455 And during a superoutburst in 2007. These observations were performed with the KANATA (…
Simultaneous MITSuME gRI monitoring of S5 0716+714
C. S. Stalin, K. S. Kawabata, M. Uemura +7
We present results of our intra-night optical flux monitoring observations of S5 0716+714 done simultaneously in gRI filters. The observations were done using Multicolor Imaging Te…
MITSuME--Multicolor Imaging Telescopes for Survey and Monstrous Explosions
T. Kotani, N. Kawai, K. Yanagisawa +25
Development of MITSuME is reported. Two 50-cm optical telescopes have been built at Akeno in Yamanashi prefecture and at Okayama Astrophysical Observatory (OAO) in Okayama prefectu…
