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…
Searching for young Jupiter analogs around AP Col: L-band high-contrast imaging of the closest pre-main sequence star
Sascha P. Quanz, Justin R. Crepp, Markus Janson +3
The nearby M-dwarf AP Col was recently identified by Riedel et al. 2011 as a pre-main sequence star (age 12 - 50 Myr) situated only 8.4 pc from the Sun. The combination of its yout…
Discovery of Small-Scale Spiral Structures in the Disk of SAO 206462 (HD 135344B): Implications for the Physical State of the Disk from Spiral Density Wave Theory
T. Muto, C. A. Grady, J. Hashimoto +59
We present high-resolution, H-band, imaging observations, collected with Subaru/HiCIAO, of the scattered light from the transitional disk around SAO 206462 (HD 135344B). Although p…
The missing cavities in the SEEDS polarized scattered light images of transitional protoplanetary disks: a generic disk model
R. Dong, R. Rafikov, Z. Zhu +53
Transitional circumstellar disks around young stellar objects have a distinctive infrared deficit around 10 microns in their Spectral Energy Distributions (SED), recently measured…
Infrared Non-detection of Fomalhaut b -- Implications for the Planet Interpretation
Markus Janson, Joe Carson, David Lafreniere +3
The nearby A4-type star Fomalhaut hosts a debris belt in the form of an eccentric ring, which is thought to be caused by dynamical influence from a giant planet companion. In 2008,…
