First images of debris disks around TWA 7, TWA 25, HD 35650, and HD 377
Élodie Choquet, Marshall D. Perrin, Christine H. Chen +15
We present the first images of four debris disks observed in scattered light around the young (4--250 Myr old) M dwarfs TWA 7 and TWA 25, the K6 star HD 35650, and the G2 star HD 3…
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…
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…
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…
Gemini Planet Imager Observations of the AU Microscopii Debris Disk: Asymmetries within One Arcsecond
Jason J. Wang, James R. Graham, Laurent Pueyo +42
We present Gemini Planet Imager (GPI) observations of AU Microscopii, a young M dwarf with an edge-on, dusty debris disk. Integral field spectroscopy and broadband imaging polarime…
IRS Spectra of Debris Disks in the Scorpius-Centaurus OB Association
Hannah Jang-Condell, Christine H. Chen, Tushar Mittal +5
We analyze Spitzer IRS spectra of 110 B-, A-, F-, and G-type stars with optically thin infrared excess in the Scorpius-Centaurus (ScoCen) OB association. The age of these stars ran…
