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…
Panoramic optical and near-infrared SETI instrument: prototype design and testing
Maren Cosens, Jérôme Maire, Shelley A. Wright +12
The Pulsed All-sky Near-infrared Optical Search for ExtraTerrestrial Intelligence (PANOSETI) is an instrument program that aims to search for fast transient signals (nano-second to…
Panoramic optical and near-infrared SETI instrument: optical and structural design concepts
Jérôme Maire, Shelley A. Wright, Maren Cosens +13
We propose a novel instrument design to greatly expand the current optical and near-infrared SETI search parameter space by monitoring the entire observable sky during all observab…
Panoramic optical and near-infrared SETI instrument: overall specifications and science program
Shelley A. Wright, Paul Horowitz, Jérôme Maire +13
We present overall specifications and science goals for a new optical and near-infrared (350 - 1650 nm) instrument designed to greatly enlarge the current Search for Extraterrestri…
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…
