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…
On-sky vibration environment for the Gemini Planet Imager and mitigation effort
Markus Hartung, Tom Hayward, Les Saddlemyer +20
The Gemini Planet Imager (GPI) entered on-sky commissioning and had its first-light at the Gemini South (GS) telescope in November 2013. GPI is an extreme adaptive optics (XAO), hi…
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…
On-instrument wavefront sensor design for the TMT infrared imaging spectrograph (IRIS) update
Jennifer Dunn, Vlad Reshetov, Jenny Atwood +6
The first light instrument on the Thirty Meter Telescope (TMT) project will be the InfraRed Imaging Spectrograph (IRIS). IRIS will be mounted on a bottom port of the facility AO in…
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…
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…
The Integral Field Spectrograph for the Gemini Planet Imager
James E. Larkin, Jeffrey K. Chilcote, Theodore Aliado +31
The Gemini Planet Imager (GPI) is a complex optical system designed to directly detect the self-emission of young planets within two arcseconds of their host stars. After suppressi…
Gemini Planet Imager One Button Approach
Jennifer Dunn, Dan Kerley, Leslie Saddlemyer +9
The Gemini Planet Imager (GPI) is an "extreme" adaptive optics coronagraph system that is now on the Gemini South telescope in Chile. This instrument is composed of three different…
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…
SPIRou: the near-infrared spectropolarimeter/high-precision velocimeter for the Canada-France-Hawaii telescope
Étienne Artigau, Driss Kouach, Jean-François Donati +30
SPIRou is a near-IR échelle spectropolarimeter and high-precision velocimeter under construction as a next-generation instrument for the Canada-France-Hawaii-Telescope. It is desig…
