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…
High-Contrast Near-Infrared Imaging Polarimetry of the Protoplanetary Disk around RY Tau
Michihiro Takami, Jennifer L. Karr, Jun Hashimoto +50
We present near-infrared coronagraphic imaging polarimetry of RY Tau. The scattered light in the circumstellar environment was imaged at H-band at a high resolution (~0".05) for th…
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.…
Mapping H-band Scattered Light Emission in the Mysterious SR21 Transitional Disk
Katherine B. Follette, Motohide Tamura, Jun Hashimoto +50
We present the first near infrared (NIR) spatially resolved images of the circumstellar transitional disk around SR21. These images were obtained with the Subaru HiCIAO camera, ada…
