First Scattered-Light Image of the Debris Disk around HD 131835 with the Gemini Planet Imager
Li-Wei Hung, Gaspard Duchêne, Pauline Arriaga +34
We present the first scattered-light image of the debris disk around HD 131835 in band using the Gemini Planet Imager. HD 131835 is a 15 Myr old A2IV star at a distance o…
Friends of Hot Jupiters III: An Infrared Spectroscopic Search for Low-Mass Stellar Companions
Danielle Piskorz, Heather A. Knutson, Henry Ngo +5
Surveys of nearby field stars indicate that stellar binaries are common, yet little is known about the effects that these companions may have on planet formation and evolution. The…
The Palomar Kernel Phase Experiment: Testing Kernel Phase Interferometry for Ground-based Astronomical Observations
Benjamin Pope, Peter Tuthill, Sasha Hinkley +5
At present, the principal limitation on the resolution and contrast of astronomical imaging instruments comes from aberrations in the optical path, which may be imposed by the Eart…
Direct imaging of an asymmetric debris disk in the HD 106906 planetary system
Paul G. Kalas, Abhijith Rajan, Jason J. Wang +53
We present the first scattered light detections of the HD 106906 debris disk using Gemini/GPI in the infrared and HST/ACS in the optical. HD 106906 is a 13 Myr old F5V star in the…
Discovery of a low-mass companion around HR3549
Dimitri Mawet, Trevor David, Michael Bottom +7
We report the discovery of a low-mass companion to HR3549, an A0V star surrounded by a debris disk with a warm excess detected by WISE at 22 m ( significance). We imaged HR…
Pictoris' inner disk in polarized light and new orbital parameters for Pictoris b
Maxwell A. Millar-Blanchaer, James R. Graham, Laurent Pueyo +54
We present -band observations of Pic with the Gemini Planet Imager's (GPI's) polarimetry mode that reveal the debris disk between ~0.3" (~6 AU) and ~1.7" (~33 AU), while sim…
