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…
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…
SEEDS Adaptive Optics Imaging of the Asymmetric Transition Disk Oph IRS 48 in Scattered Light
Katherine B. Follette, Carol A. Grady, Jeremy R. Swearingen +60
We present the first resolved near infrared imagery of the transition disk Oph IRS 48 (WLY 2-48), which was recently observed with ALMA to have a strongly asymmetric sub-millimeter…
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 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 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.…
The Structure of Pre-transitional Protoplanetary Disks I: Radiative Transfer Modeling of the Disk+Cavity in the PDS 70 system
Ruobing Dong, Jun Hashimoto, Roman Rafikov +49
Through detailed radiative transfer modeling, we present a disk+cavity model to simultaneously explain both the SED and Subaru H-band polarized light imaging for the pre-transition…
A Common Proper Motion Stellar Companion to HAT-P-7
Norio Narita, Yasuhiro H. Takahashi, Masayuki Kuzuhara +51
We report that HAT-P-7 has a common proper motion stellar companion. The companion is located at arcsec to the east and estimated as an M5.5V dwarf based on its colors. W…
Discovery of Small-Scale Spiral Structures in the Disk of SAO 206462 (HD 135344B): Implications for the Physical State of the Disk from Spiral Density Wave Theory
T. Muto, C. A. Grady, J. Hashimoto +59
We present high-resolution, H-band, imaging observations, collected with Subaru/HiCIAO, of the scattered light from the transitional disk around SAO 206462 (HD 135344B). Although p…
The missing cavities in the SEEDS polarized scattered light images of transitional protoplanetary disks: a generic disk model
R. Dong, R. Rafikov, Z. Zhu +53
Transitional circumstellar disks around young stellar objects have a distinctive infrared deficit around 10 microns in their Spectral Energy Distributions (SED), recently measured…
Search for Outer Massive Bodies around Transiting Planetary Systems: Candidates of Faint Stellar Companions around HAT-P-7
Norio Narita, Tomoyuki Kudo, Carolina Bergfors +46
We present results of direct imaging observations for HAT-P-7 taken with the Subaru HiCIAO and the Calar Alto AstraLux. Since the close-in transiting planet HAT-P-7b was reported t…
