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…
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…
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…
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…
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…
Asymmetries in adaptive optics point spread functions
Alexander Madurowicz, Bruce Macintosh, Vanessa P. Bailey +45
An explanation for the origin of asymmetry along the preferential axis of the PSF of an AO system is developed. When phase errors from high altitude turbulence scintillate due to F…
Status of the Keck Planet Imager and Characterizer Phase II Development
Jacklyn Pezzato, Nemanja Jovanovic, Dimitri Mawet +15
The Keck Planet Imager and Characterizer comprises of a series of upgrades to the Keck II adaptive optics system and instrument suite to improve the direct imaging and high resolut…
The vortex fiber nulling mode of the Keck Planet Imager and Characterizer (KPIC)
Daniel Echeverri, Garreth Ruane, Nemanja Jovanovic +8
The Keck Planet Imager and Characterizer (KPIC) is an upgrade to the Keck II adaptive optics system that includes an active fiber injection unit (FIU) for efficiently routing light…
Vortex fiber nulling for exoplanet observations: conceptual design, theoretical performance, and initial scientific yield predictions
Garreth Ruane, Daniel Echeverri, Nemanja Jovanovic +5
Vortex fiber nulling (VFN) is a method that may enable the detection and characterization of exoplanets at small angular separations (0.5-2 ) with ground- and space-based tele…
TESS Hunt for Young and Maturing Exoplanets (THYME): A planet in the 45 Myr Tucana-Horologium association
Elisabeth R. Newton, Andrew W. Mann, Benjamin M. Tofflemire +49
Young exoplanets are snapshots of the planetary evolution process. Planets that orbit stars in young associations are particularly important because the age of the planetary system…
Cold Debris Disks as Strategic Targets for the 2020s
John Debes, Elodie Choquet, Virginie C. Faramaz +19
Cold debris disks (T200 K) are analogues to the dust in the Solar System's Kuiper belt--dust generated from the evaporation and collision of minor bodies perturbed by planets, o…
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…
Imaging Cool Giant Planets in Reflected Light: Science Investigations and Synergy with Habitable Planets
Mark Marley, Nikole Lewis, Giada Arney +38
Planned astronomical observatories of the 2020s will be capable of obtaining reflected light photometry and spectroscopy of cool extrasolar giant planets. Here we explain that such…
The Demographics and Atmospheres of Giant Planets with the ELTs
Brendan Bowler, Steph Sallum, Alan Boss +23
