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…
CHARIS Science: Performance Simulations for the Subaru Telescope's Third-Generation of Exoplanet Imaging Instrumentation
Timothy D. Brandt, Michael W. McElwain, Markus Janson +21
We describe the expected scientific capabilities of CHARIS, a high-contrast integral-field spectrograph (IFS) currently under construction for the Subaru telescope. CHARIS is part…
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…
A Statistical Analysis of SEEDS and Other High-Contrast Exoplanet Surveys: Massive Planets or Low-Mass Brown Dwarfs?
Timothy D. Brandt, Michael W. McElwain, Edwin L. Turner +50
We conduct a statistical analysis of a combined sample of direct imaging data, totalling nearly 250 stars. The stars cover a wide range of ages and spectral types, and include five…
High-Resolution Submillimeter and Near-Infrared Studies of the Transition Disk around Sz 91
Takashi Tsukagoshi, Munetake Momose, Jun Hashimoto +55
To reveal the structures of a transition disk around a young stellar object in Lupus, Sz 91, we have performed aperture synthesis 345 GHz continuum and CO(3--2) observations with t…
