Direct Imaging Detection of Methane in the Atmosphere of GJ 504 b
M. Janson, T. Brandt, M. Kuzuhara +54
Most exoplanets detected by direct imaging so far have been characterized by relatively hot (> ~1000 K) and cloudy atmospheres. A surprising feature in some of their atmospheres ha…
A Discovery of a Candidate Companion to a Transiting System KOI-94: A Direct Imaging Study for a Possibility of a False Positive
Yasuhiro H. Takahashi, Norio Narita, Teruyuki Hirano +49
We report a discovery of a companion candidate around one of {\it Kepler} Objects of Interest (KOIs), KOI-94, and results of our quantitative investigation of the possibility that…
Characterization of the gaseous companion κ Andromedae b: New Keck and LBTI high-contrast observations
M. Bonnefoy, T. Currie, G. -D. Marleau +64
We previously reported the direct detection of a low mass companion at a projected separation of 55+-2 AU around the B9 type star κ Andromedae. The properties of the system (mass r…
Direct Imaging of a Cold Jovian Exoplanet in Orbit around the Sun-like Star GJ 504
M. Kuzuhara, M. Tamura, T. Kudo +54
Several exoplanets have recently been imaged at wide separations of >10 AU from their parent stars. These span a limited range of ages (<50 Myr) and atmospheric properties, with te…
Direct Imaging Search for Extrasolar Planets in the Pleiades
Kodai Yamamoto, Taro Matsuo, Hiroshi Shibai +53
We carried out an imaging survey for extrasolar planets around stars in the Pleiades (125 Myr, 135 pc) in the and bands using HiCIAO combined with the adaptive optics,…
The SEEDS Direct Imaging Survey for Planets and Scattered Dust Emission in Debris Disk Systems
Markus Janson, Timothy D. Brandt, Amaya Moro-Martin +49
Debris disks around young main-sequence stars often have gaps and cavities which for a long time have been interpreted as possibly being caused by planets. In recent years, several…
The Moving Group Targets of the SEEDS High-Contrast Imaging Survey of Exoplanets and Disks: Results and Observations from the First Three Years
Timothy D. Brandt, Masayuki Kuzuhara, Michael W. McElwain +52
We present results from the first three years of observations of moving group targets in the SEEDS high-contrast imaging survey of exoplanets and disks using the Subaru telescope.…
