Dynamical Constraints on the HR 8799 Planets with GPI
Jason J. Wang, James R. Graham, Rebekah Dawson +52
The HR 8799 system uniquely harbors four young super-Jupiters whose orbits can provide insights into the system's dynamical history and constrain the masses of the planets themselv…
Characterization of lemniscate atmospheric aberrations in Gemini Planet Imager data
Alexander Madurowicz, Bruce A. Macintosh, Jean-Baptiste Ruffio +5
A semi analytic framework for simulating the effects of atmospheric seeing in Adaptive Optics systems on an 8-m telescope is developed with the intention of understanding the origi…
Air, Telescope, and Instrument Temperature Effects on the Gemini Planet Imager's Image Quality
Melisa Tallis, Vanessa P. Bailey, Bruce Macintosh +5
The Gemini Planet Imager (GPI) is a near-infrared instrument that uses Adaptive Optics (AO), a coronagraph, and advanced data processing techniques to achieve very high contrast im…
The Gemini Planet Imager: Looking back over five years and forward to the future
Bruce Macintosh, Jeffrey K. Chilcote, Vanessa P. Bailey +10
The Gemini Planet Imager (GPI), a coronagraphic adaptive optics instrument designed for spectroscopy of extrasolar planets, had first light in 2013[13]. After five years, GPI has o…
Direct Imaging of the HD 35841 Debris Disk: A Polarized Dust Ring from Gemini Planet Imager and an Outer Halo from HST/STIS
Thomas M. Esposito, Gaspard Duchêne, Paul Kalas +55
We present new high resolution imaging of a light-scattering dust ring and halo around the young star HD 35841. Using spectroscopic and polarimetric data from the Gemini Planet Ima…
GPI spectra of HR 8799 c, d, and e from 1.5 to 2.4m with KLIP Forward Modeling
Alexandra Z. Greenbaum, Laurent Pueyo, Jean-Baptiste Ruffio +51
We explore KLIP forward modeling spectral extraction on Gemini Planet Imager coronagraphic data of HR 8799, using PyKLIP and show algorithm stability with varying KLIP parameters.…
Automated data processing architecture for the Gemini Planet Imager Exoplanet Survey
Jason Wang, Marshall Perrin, Dmitry Savransky +49
The Gemini Planet Imager Exoplanet Survey (GPIES) is a multi-year direct imaging survey of 600 stars to discover and characterize young Jovian exoplanets and their environments. We…
