The Structure of Pre-transitional Protoplanetary Disks. II. Azimuthal Asymmetries, Different Radial Distributions of Large and Small Dust Grains in PDS~70
J. Hashimoto, T. Tsukagoshi, J. M. Brown +54
The formation scenario of a gapped disk, i.e., transitional disk, and its asymmetry is still under debate. Proposed scenarios such as disk-planet interaction, photoevaporation, gra…
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…
Recovery of the Candidate Protoplanet HD 100546 b with Gemini/NICI and Detection of Additional (Planet-Induced?) Disk Structure at Small Separations
Thayne Currie, Takayuki Muto, Tomoyuki Kudo +23
We report the first independent, second-epoch (re-)detection of a directly-imaged protoplanet candidate. Using high-contrast imaging of HD 100546 taken with the Near-Inf…
Indications of M-dwarf Deficits in the Halo and Thick Disk of the Galaxy
Mihoko Konishi, Hiroshi Shibai, Takahiro Sumi +55
We compared the number of faint stars detected in deep survey fields with the current stellar distribution model of the Galaxy and found that the detected number in the H band is s…
Surface Geometry of Protoplanetary Disks Inferred From Near-Infrared Imaging Polarimetry
Michihiro Takami, Yasuhiro Hasegawa, Takayuki Muto +58
We present a new method of analysis for determining the surface geometry of five protoplanetary disks observed with near-infrared imaging polarimetry using Subaru-HiCIAO. Using as…
Lyot-based Low Order Wavefront Sensor: Implementation on the Subaru Coronagraphic Extreme Adaptive Optics System and its Laboratory Performance
Garima Singh, Olivier Guyon, Pierre Baudoz +5
High throughput, low inner working angle (IWA) phase masks coronagraphs are essential to directly image and characterize (via spectroscopy) earth-like planets. However, the perform…
