Direct Imaging Discovery of a `Super-Jupiter' Around the late B-Type Star Kappa And

J. Carson, C. Thalmann, M. Janson +52

We present the direct imaging discovery of an extrasolar planet, or possible low-mass brown dwarf, at a projected separation of 55 +/- 2 AU (1.058 +/- 0.007 arcsec) from the B9-typ…

Subaru Imaging of Asymmetric Features in a Transitional Disk in Upper Scorpius

S. Mayama, J. Hashimoto, T. Muto +52

We report high-resolution (0.07 arcsec) near-infrared polarized intensity images of the circumstellar disk around the star 2MASS J16042165-2130284 obtained with HiCIAO mounted on t…

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…

New Techniques for High-Contrast Imaging with ADI: the ACORNS-ADI SEEDS Data Reduction Pipeline

Timothy D. Brandt, Michael W. McElwain, Edwin L. Turner +44

We describe Algorithms for Calibration, Optimized Registration, and Nulling the Star in Angular Differential Imaging (ACORNS-ADI), a new, parallelized software package to reduce hi…

Polarimetric Imaging of Large Cavity Structures in the Pre-transitional Protoplanetary Disk around PDS 70: Observations of the disk

Jun Hashimoto, Ruobing Dong, Tomoyuki Kudo +52

We present high resolution H-band polarized intensity (PI; FWHM = 0."1: 14 AU) and L'-band imaging data (FWHM = 0."11: 15 AU) of the circumstellar disk around the weak-lined T Taur…
