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…
Opto-Mechanical Design of ShaneAO: the Adaptive Optics System for the 3-meter Shane Telescope
Christopher Ratliff, Jerry Cabak, Donald Gavel +8
A Cassegrain mounted adaptive optics instrument presents unique challenges for opto-mechanical design. The flexure and temperature tolerances for stability are tighter than those o…
ShaneAO: wide science spectrum adaptive optics system for the Lick Observatory
Donald Gavel, Renate Kupke, Daren Dillon +14
A new high-order adaptive optics system is now being commissioned at the Lick Observatory Shane 3-meter telescope in California. This system uses a high return efficiency sodium be…
Swimming with ShARCS: Comparison of On-sky Sensitivity With Model Predictions for ShaneAO on the Lick Observatory 3-meter Telescope
Srikar Srinath, Rosalie McGurk, Constance Rockosi +10
The Lick Observatory's Shane 3-meter telescope has been upgraded with a new infrared instrument (ShARCS - Shane Adaptive optics infraRed Camera and Spectrograph) and dual-deformabl…
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…
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…
