Near-Infrared Imaging Polarimetry of Inner Region of GG Tau A Disk
Yi Yang, Jun Hashimoto, Saeko S. Hayashi +51
By performing non-masked polarization imaging with Subaru/HiCIAO, polarized scattered light from the inner region of the disk around the GG Tau A system was successfully detected i…
A Substellar Companion to Pleiades HII 3441
Mihoko Konishi, Taro Matsuo, Kodai Yamamoto +55
We find a new substellar companion to the Pleiades member star, Pleiades HII 3441, using the Subaru telescope with adaptive optics. The discovery is made as part of the high-contra…
Thermal Infrared Imaging and Atmospheric Modeling of VHS J125601.92-125723.9 b: Evidence for Moderately Thick Clouds and Equilibrium Carbon Chemistry in a Hierarchical Triple System
Evan A. Rich, Thayne Currie, John P. Wisniewski +5
We present and analyze Subaru/IRCS L' and M' images of the nearby M dwarf VHS J125601.92-125723.9 (VHS 1256), which was recently claimed to have a ~11 M_Jup companion (VHS 1256 b)…
Polarimetry and flux distribution in the debris disk around HD 32297
R. Asensio-Torres, M. Janson, J. Hashimoto +49
We present high-contrast angular differential imaging (ADI) observations of the debris disk around HD 32297 in H-band, as well as the first polarimetric images for this system in p…
SPOTS: The Search for Planets Orbiting Two Stars: II. First constraints on the frequency of sub-stellar companions on wide circumbinary orbits
Mariangela Bonavita, Silvano Desidera, Christian Thalmann +4
A large number of direct imaging surveys for exoplanets have been performed in recent years, yielding the first directly imaged planets and providing constraints on the prevalence…
High Contrast Imaging with Spitzer : Constraining the Frequency of Giant Planets out to 1000 AU separations
Stephen Durkan, Markus Janson, Joseph Carson
We report results of a re-analysis of archival Spitzer IRAC direct imaging surveys encompassing a variety of nearby stars. Our sample is generated from the combined observations of…
High-Contrast Imaging of Intermediate-Mass Giants with Long-Term Radial Velocity Trends
Tsuguru Ryu, Bun'ei Sato, Masayuki Kuzuhara +62
A radial velocity (RV) survey for intermediate-mass giants has been operated for over a decade at Okayama Astrophysical Observatory (OAO). The OAO survey has revealed that some gia…
The SEEDS High Contrast Imaging Survey of Exoplanets around Young Stellar Objects
Taichi Uyama, Jun Hashimoto, Masayuki Kuzuhara +49
We present high-contrast observations of 68 young stellar objects (YSOs) explored as part of the SEEDS survey on the Subaru telescope. Our targets are very young (10 Myr) stars,…
Discovery of an Inner Disk Component around HD 141569 A
Mihoko Konishi, Carol A. Grady, Glenn Schneider +20
We report the discovery of a scattering component around the HD 141569 A circumstellar debris system, interior to the previously known inner ring. The discovered inner disk compone…
Near-Infrared Imaging Polarimetry of LkCa 15: A Possible Warped Inner Disk
Daehyeon Oh, Jun Hashimoto, Motohide Tamura +48
We present high-contrast H-band polarized intensity images of the transitional disk around the young solar-like star LkCa 15. By utilizing Subaru/HiCIAO for polarimetric differenti…
