The K2-ESPRINT Project III: A Close-in Super-Earth around a Metal-rich Mid-M Dwarf
Teruyuki Hirano, Akihiko Fukui, Andrew W. Mann +18
We validate a planet on a close-in orbit ( days) around K2-28 (EPIC 206318379), a metal-rich M4-type dwarf in the Campaign 3 fiel…
Near-Infrared Polarimetry of the GG Tauri A Binary System
Yoichi Itoh, Yumiko Oasa, Tomoyuki Kudo +47
A high angular resolution near-infrared polarized-intensity image of the GG Tau A binary system was obtained with the Subaru Telescope. The image shows the circumbinary disk scatte…
Near-IR Polarized Scattered Light Imagery of the DoAr 28 Transitional Disk
Evan A. Rich, John P. Wisniewski, Satoshi Mayama +52
We present the first spatially resolved polarized scattered light H-band detection of the DoAr 28 transitional disk. Our two epochs of imagery detect the scattered light disk from…
Detailed structure of the outer disk around HD 169142 with polarized light in H-band
Munetake Momose, Ayaka Morita, Misato Fukagawa +59
Coronagraphic imagery of the circumstellar disk around HD 169142 in H-band polarized intensity (PI) with Subaru/HiCIAO is presented. The emission scattered by dust particles at the…
Near-IR High-Resolution Imaging Polarimetry of the SU Aur Disk: Clues for Tidal Tails?
Jerome de Leon, Michihiro Takami, Jennifer L. Karr +53
We present new high-resolution (0\farcs09) -band imaging observations of the circumstellar disk around the T Tauri star SU Aur. Our observations with Subaru-HiCIAO have re…
The K2-ESPRINT Project. I. Discovery of the Disintegrating Rocky Planet K2-22b with a Cometary Head and Leading Tail
R. Sanchis-Ojeda, S. Rappaport, E. Pallé +28
We present the discovery of a transiting exoplanet candidate in the K2 Field-1 with an orbital period of 9.1457 hr: K2-22b. The highly variable transit depths, ranging from 0…
Discovery of a Disk Gap Candidate at 20 AU in TW Hydrae
E. Akiyama, T. Muto, N. Kusakabe +53
We present a new Subaru/HiCIAO high-contrast H-band polarized intensity (PI) image of a nearby transitional disk associated with TW Hydrae. The scattered light from the disk was de…
