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…
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.…
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…
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…
Discovery and spectroscopy of the young Jovian planet 51 Eri b with the Gemini Planet Imager
B. Macintosh, J. R. Graham, T. Barman +85
Directly detecting thermal emission from young extrasolar planets allows measurement of their atmospheric composition and luminosity, which is influenced by their formation mechani…
