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…
WFIRST-AFTA Coronagraphic Operations: Lessons Learned from the Hubble Space Telescope and the James Webb Space Telescope
John H. Debes, Marie Ygouf, Elodie Choquet +8
The coronagraphic instrument currently proposed for the WFIRST-AFTA mission will be the first example of a space-based coronagraph optimized for extremely high contrasts that are r…
An M-dwarf star in the transition disk of Herbig HD 142527; Physical parameters and orbital elements
S. Lacour, B. Biller, A. Cheetham +29
HD 142527A is one of the most studied Herbig Ae/Be stars with a transitional disk, as it has the largest imaged gap in any protoplanetary disk: the gas is cleared from 30 to 90 AU.…
Active compensation of aperture discontinuities for WFIRST-AFTA: analytical and numerical comparison of propagation methods and preliminary results with a WFIRST-AFTA-like pupil
Johan Mazoyer, Laurent Pueyo, Colin Norman +3
The new frontier in the quest for the highest contrast levels in the focal plane of a coronagraph is now the correction of the large diffractive artifacts effects introduced at the…
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…
Archival Legacy Investigations of Circumstellar Environments (ALICE): Statistical assessment of point source detections
É. Choquet, L. Pueyo, R. Soummer +5
The ALICE program, for Archival Legacy Investigation of Circumstellar Environment, is currently conducting a virtual survey of about 400 stars, by re-analyzing the HST-NICMOS coron…
Astrometric Confirmation and Preliminary Orbital Parameters of the Young Exoplanet 51 Eridani b with the Gemini Planet Imager
Robert J. De Rosa, Eric L. Nielsen, Sarah C. Blunt +47
We present new Gemini Planet Imager observations of the young exoplanet 51 Eridani b which provide further evidence that the companion is physically associated with 51 Eridani. Com…
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…
Characterizing the Atmospheres of the HR8799 Planets with HST/WFC3
Abhijith Rajan, Travis S. Barman, Remi Soummer +7
We present results from a Hubble Space Telescope (HST) program characterizing the atmospheres of the outer two planets, in the HR8799 system. The images were taken over 15 orbits i…
Know the Star, Know the Planet. V. Characterization of the Stellar Companion to the Exoplanet Host HD 177830
Lewis C. Roberts, Rebecca Oppenheimer, Justin R. Crepp +21
HD 177830 is an evolved K0IV star with two known exoplanets. In addition to the planetary companions it has a late-type stellar companion discovered with adaptive optics imagery. W…
