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…
The Infrared Imaging Spectrograph (IRIS) for TMT: Volume phase holographic grating performance testing and discussion
Shaojie Chen, Elliot Meyer, Shelley A. Wright +5
Maximizing the grating efficiency is a key goal for the first light instrument IRIS (Infrared Imaging Spectrograph) currently being designed to sample the diffraction limit of the…
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…
A near-infrared SETI experiment: probability distribution of false coincidences
Jérôme Maire, Shelley A. Wright, Dan Werthimer +5
A Search for Extraterrestrial Life (SETI), based on the possibility of interstellar communication via laser signals, is being designed to extend the search into the near-infrared s…
A near-infrared SETI experiment: instrument overview
Shelley A. Wright, Dan Werthimer, Richard R. Treffers +7
We are designing and constructing a new SETI (Search for Extraterrestrial Intelligence) instrument to search for direct evidence of interstellar communications via pulsed laser sig…
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…
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 Observational Calibrations VII: On-Sky Polarimetric Performance of the Gemini Planet Imager
Sloane J. Wiktorowicz, Max Millar-Blanchaer, Marshall D. Perrin +17
We present on-sky polarimetric observations with the Gemini Planet Imager (GPI) obtained at straight Cassegrain focus on the Gemini South 8-m telescope. Observations of polarimetri…
