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…
EXCEDE Technology Development III: First Vacuum Tests
Ruslan Belikov, Julien Lozi, Eugene Pluzhnik +13
This paper is the third in the series on the technology development for the EXCEDE (EXoplanetary Circumstellar Environments and Disk Explorer) mission concept, which in 2011 was se…
Experimental study of a low-order wavefront sensor for high-contrast coronagraphic imagers: results in air and in vacuum
Julien Lozi, Ruslan Belikov, Sandrine J. Thomas +4
For the technology development of the mission EXCEDE (EXoplanetary Circumstellar Environments and Disk Explorer) - a 0.7 m telescope equipped with a Phase-Induced Amplitude Apodiza…
Characterization of the Atmospheric Dispersion Corrector of the Gemini Planet Imager
Pascale Hibon, Sandrine Thomas, Jennifer Dunn +18
An Atmospheric Dispersion Corrector (ADC) uses a double-prism arrangement to nullify the vertical chromatic dispersion introduced by the atmosphere at non-zero zenith distances. Th…
Gemini Planet Imager integration to the Gemini South telescope software environment
Fredrik T. Rantakyrö, Andrew Cardwell, Jeffrey Chilcote +18
The Gemini Planet Imager is an extreme AO instrument with an integral field spectrograph (IFS) operating in Y, J, H, and K bands. Both the Gemini telescope and the GPI instrument a…
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…
