Upper limits for Mass and Radius of objects around Proxima Cen from SPHERE/VLT
D. Mesa, A. Zurlo, J. Milli +36
The recent discovery of an earth-like planet around Proxima Centauri has drawn much attention to this star and its environment. We performed a series of observations of Proxima Cen…
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…
Multiple rings in the transition disk and companion candidates around RXJ1615.3-3255. High contrast imaging with VLT/SPHERE
J. de Boer, G. Salter, M. Benisty +36
We search for signs of ongoing planet-disk interaction and study the distribution of small grains at the surface of the transition disk around RXJ1615.3-3255 (RX J1615). We observe…
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…
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,…
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…
