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 VIII: Characterization and Role of Satellite Spots
Jason J. Wang, Abhijith Rajan, James R. Graham +20
The Gemini Planet Imager (GPI) combines extreme adaptive optics, an integral field spectrograph, and a high performance coronagraph to directly image extrasolar planets in the near…
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…
Companions of Stars: From Other Stars to Brown Dwarfs to Planets: The Discovery of the First Methane Brown Dwarf
B. R. Oppenheimer
The discovery of the first methane brown dwarf provides a framework for describing the important advances in both fundamental physics and astrophysics that are due to the study of…
Electric Field Conjugation with the Project 1640 coronagraph
Eric Cady, Christoph Baranec, Charles Beichman +25
The Project 1640 instrument on the 200-inch Hale telescope at Palomar Observatory is a coronagraphic instrument with an integral field spectrograph at the back end, designed to fin…
The Kappa Andromedae System: New Constraints on the Companion Mass, System Age & Further Multiplicity
Sasha Hinkley, Laurent Pueyo, Jacqueline K. Faherty +29
Kappa Andromedae is a B9IVn star at 52 pc for which a faint substellar companion separated by 55 AU was recently announced. In this work, we present the first spectrum of the compa…
