The Gemini Planet Imager Exoplanet Survey: Dynamical Mass of the Exoplanet beta Pictoris b from Combined Direct Imaging and Astrometry
Eric L. Nielsen, Robert J. De Rosa, Jason J. Wang +51
We present new observations of the planet beta Pictoris b from 2018 with GPI, the first GPI observations following conjunction. Based on these new measurements, we perform a joint…
Detection of a low-mass stellar companion to the accelerating A2IV star HR 1645
Robert J. De Rosa, Eric L. Nielsen, Julien Rameau +50
The \, Myr A2IV star HR 1645 has one of the most significant low-amplitude accelerations of nearby early-type stars measured from a comparison of the {\it Hipparcos} and {…
An updated visual orbit of the directly-imaged exoplanet 51 Eridani b and prospects for a dynamical mass measurement with Gaia
Robert J. De Rosa, Eric L. Nielsen, Jason J. Wang +52
We present a revision to the visual orbit of the young, directly-imaged exoplanet 51 Eridani b using four years of observations with the Gemini Planet Imager. The relative astromet…
Revised Astrometric Calibration of the Gemini Planet Imager
Robert J. De Rosa, Meiji M. Nguyen, Jeffrey Chilcote +49
We present a revision to the astrometric calibration of the Gemini Planet Imager (GPI), an instrument designed to achieve the high contrast at small angular separations necessary t…
An Exo-Kuiper Belt and An Extended Halo around HD 191089 in Scattered Light
Bin Ren, Élodie Choquet, Marshall D. Perrin +70
We have obtained Hubble Space Telescope STIS and NICMOS, and Gemini/GPI scattered light images of the HD 191089 debris disk. We identify two spatial components: a ring resembling K…
The Gemini Planet Imager Exoplanet Survey: Giant Planet and Brown Dwarf Demographics From 10-100 AU
Eric L. Nielsen, Robert J. De Rosa, Bruce Macintosh +62
We present a statistical analysis of the first 300 stars observed by the Gemini Planet Imager Exoplanet Survey (GPIES). This subsample includes six detected planets and three brown…
