Imaging the 44 AU Kuiper Belt-analogue debris ring around HD 141569A with GPI polarimetry
J. S. Bruzzone, S. Metchev, G. Duchene +53
We present the first polarimetric detection of the inner disk component around the pre-main sequence B9.5 star HD 141569A. Gemini Planet Imager H-band (1.65 micron) polarimetric di…
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…
First Resolved Scattered-Light Images of Four Debris Disks in Scorpius-Centaurus with the Gemini Planet Imager
Justin Hom, Jennifer Patience, Thomas M. Esposito +57
We present the first spatially resolved scattered-light images of four debris disks around members of the Scorpius-Centaurus (Sco-Cen) OB Association with high-contrast imaging and…
Radial Velocity Measurements of HR 8799 b and c with Medium Resolution Spectroscopy
Jean-Baptiste Ruffio, Bruce Macintosh, Quinn M. Konopacky +6
High-contrast medium resolution spectroscopy has been used to detect molecules such as water and carbon monoxide in the atmospheres of gas giant exoplanets. In this work, we show h…
The Possible Astrometric Signature of a Planetary-mass Companion to the Nearby Young Star TW Piscis Austrini (Fomalhaut B): Constraints from Astrometry, Radial Velocities, and Direct Imaging
Robert J. De Rosa, Thomas M. Esposito, Lea A. Hirsch +5
We present constraints on the presence of substellar companions to the nearby ( pc), young ( Myr) K4Ve star TW Piscis Austrini, the wide (0.3 pc) companio…
orbitize!: A Comprehensive Orbit-fitting Software Package for the High-contrast Imaging Community
Sarah Blunt, Jason Wang, Isabel Angelo +10
orbitize! is an open-source, object-oriented software package for fitting the orbits of directly-imaged objects. It packages the Orbits for the Impatient (OFTI) algorithm and a par…
