The LEECH Exoplanet Imaging Survey. Further constraints on the planet architecture of the HR 8799 system
A. -L. Maire, A. J. Skemer, P. M. Hinz +36
Context. Astrometric monitoring of directly-imaged exoplanets allows the study of their orbital parameters and system architectures. Because most directly-imaged planets have long…
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…
The First H-band Spectrum of the Massive Gas Giant Planet beta Pictoris b with the Gemini Planet Imager
Jeffrey Chilcote, Travis Barman, Michael P. Fitzgerald +43
Using the recently installed Gemini Planet Imager (GPI), we have taken the first H-band spectrum of the planetary companion to the nearby young star beta Pictoris. GPI is designed…
High contrast imaging at the LBT: the LEECH exoplanet imaging survey
Andrew J. Skemer, Philip Hinz, Simone Esposito +34
In Spring 2013, the LEECH (LBTI Exozodi Exoplanet Common Hunt) survey began its 130-night campaign from the Large Binocular Telescope (LBT) atop Mt Graham, Arizona. This surv…
GPI PSF subtraction with TLOCI: the next evolution in exoplanet/disk high-contrast imaging
Christian Marois, Carlos Correia, Raphael Galicher +4
To directly image exoplanets and faint circumstellar disks, the noisy stellar halo must be suppressed to a high level. To achieve this feat, the angular differential imaging observ…
Gemini Planet Imager Observational Calibrations VIII: Characterization and Role of Satellite Spots
Jason J. Wang, Abhijith Rajan, James R. Graham +20
The Gemini Planet Imager (GPI) combines extreme adaptive optics, an integral field spectrograph, and a high performance coronagraph to directly image extrasolar planets in the near…
Gemini Planet Imager Observational Calibrations VI: Photometric and Spectroscopic Calibration for the Integral Field Spectrograph
Jérôme Maire, Patrick J. Ingraham, Robert J. De Rosa +20
The Gemini Planet Imager (GPI) is a new facility instrument for the Gemini Observatory designed to provide direct detection and characterization of planets and debris disks around…
Gemini Planet Imager Observational Calibrations V: Astrometry and Distortion
Quinn M. Konopacky, Sandrine J. Thomas, Bruce A. Macintosh +24
We present the results of both laboratory and on sky astrometric characterization of the Gemini Planet Imager (GPI). This characterization includes measurement of the pixel scale o…
Gemini Planet Imager Observational Calibrations I: Overview of the GPI Data Reduction Pipeline
Marshall D. Perrin, Jérôme Maire, Patrick Ingraham +35
The Gemini Planet Imager (GPI) has as its science instrument an infrared integral field spectrograph/polarimeter (IFS). Integral field spectrographs are scientificially powerful bu…
On-sky performance during verification and commissioning of the Gemini Planet Imager's adaptive optics system
Lisa A. Poyneer, Robert J. De Rosa, Bruce Macintosh +15
The Gemini Planet Imager instrument's adaptive optics (AO) subsystem was designed specifically to facilitate high-contrast imaging. It features several new technologies, including…
The Gemini Planet Imager: First Light
Bruce Macintosh, James R. Graham, Patrick Ingraham +44
The Gemini Planet Imager (GPI) is a dedicated facility for directly imaging and spectroscopically characterizing extrasolar planets. It combines a very high-order adaptive optics s…
Does the Debris Disk around HD 32297 Contain Cometary Grains?
Timothy J. Rodigas, John H. Debes, Philip M. Hinz +13
We present an adaptive optics imaging detection of the HD 32297 debris disk at L' (3.8 \microns) obtained with the LBTI/LMIRcam infrared instrument at the LBT. The disk is detected…
