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…
Detection of solar-like oscillations in the bright red giant stars Psc and Tau from a 190-day high-precision spectroscopic multisite campaign
P. G. Beck, E. Kambe, M. Hillen +35
Red giants are evolved stars which exhibit solar-like oscillations. Although a multitude of stars have been observed with space telescopes, only a handful of red-giant stars were t…
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…
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…
Dusty ERO Search behind Two Massive Clusters
Tadafumi Takata, Nobunari Kashikawa, Kouichiro Nakanishi +15
We performed deep K'-band imaging observations of 2 massive clusters, MS 0451.6-0305 at z = 0.55 and MS 0440.5+0204 at z = 0.19, for searching counterparts of the faint sub-mm sour…
Decomposition of the Superwind in M82
Youichi Ohyama, Yoshiaki Taniguchi, Masanori Iye +16
We present new optical images (, , and H) of the archetypical starburst/superwind galaxy M82 obtained with the 8.2 m Subaru Telescope to reveal new detailed structures of…
A New High-Redshift Lyman alpha Emitter: Possible Superwind Galaxy at z = 5.69
M. Ajiki, Y. Taniguchi, T. Murayama +33
During the course of our deep optical imaging survey for Ly alpha emitters at z approximately 5.7 in the field around the z=5.74 quasar SDSSp J104433.04-012502.2, we have found a c…
Photospheric Abundances of Volatile and Refractory Elements in Planet-Harboring Stars
Y. Takeda, B. Sato, E. Kambe +16
By using the high-dispersion spectra of 14 bright planet-harboring stars (along with 4 reference stars) observed with the new coude echelle spectrograph at Okayama Astrophysical Ob…
A Shock-Induced Pair of Superbubbles in the High-Redshift Powerful Radio Galaxy MRC 0406-244
