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…
Gemini Planet Imager Observational Calibrations III: Empirical Measurement Methods and Applications of High-Resolution Microlens PSFs
Patrick Ingraham, Jean-Baptiste Ruffio, Marshall D. Perrin +5
The newly commissioned Gemini Planet Imager (GPI) combines extreme adaptive optics, an advanced coronagraph, precision wavefront control and a lenslet-based integral field spectrog…
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…
Gemini Planet Imager Observational Calibrations II: Detector Performance and Calibration
Patrick Ingraham, Marshall D. Perrin, Naru Sadakuni +7
The Gemini Planet Imager is a newly commissioned facility instrument designed to measure the near-infrared spectra of young extrasolar planets in the solar neighborhood and obtain…
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…
