Status and performance of the Gemini Planet Imager adaptive optics system
Vanessa P. Bailey, Lisa A. Poyneer, Bruce A. Macintosh +14
The Gemini Planet Imager is a high-contrast near-infrared instrument specifically designed to image exoplanets and circumstellar disks over a narrow field of view. We use science d…
Discovery of a Substellar Companion to the Nearby Debris Disk Host HR 2562
Quinn M. Konopacky, Julien Rameau, Gaspard Duchene +54
We present the discovery of a brown dwarf companion to the debris disk host star HR 2562. This object, discovered with the Gemini Planet Imager (GPI), has a projected separation of…
The Orbit and Transit Prospects for Pictoris b constrained with One Milliarcsecond Astrometry
Jason J. Wang, James R. Graham, Laurent Pueyo +51
A principal scientific goal of the Gemini Planet Imager (GPI) is obtaining milliarcsecond astrometry to constrain exoplanet orbits. However, astrometry of directly imaged exoplanet…
The VAST Survey - IV. A wide brown dwarf companion to the A3V star Delphini
R. J. De Rosa, J. Patience, K. Ward-Duong +10
We report the discovery of a wide co-moving substellar companion to the nearby ( pc) A3V star Delphini based on imaging and follow-up spectroscopic observations o…
Gemini Planet Imager Spectroscopy of the HR 8799 planets c and d
Patrick Ingraham, Mark S. Marley, Didier Saumon +43
During the first-light run of the Gemini Planet Imager (GPI) we obtained K-band spectra of exoplanets HR 8799 c and d. Analysis of the spectra indicates that planet d may be warmer…
Polarimetry with the Gemini Planet Imager: Methods, Performance at First Light, and the Circumstellar Ring around HR 4796A
Marshall D. Perrin, Gaspard Duchene, Max Millar-Blanchaer +41
We present the first results from the polarimetry mode of the Gemini Planet Imager (GPI), which uses a new integral field polarimetry architecture to provide high contrast linear p…
