Giant Impacts and Debris Disk Morphology
Joshua W. Jones, Eugene Chiang, Gaspard Duchene +2
Certain debris disks have non-axisymmetric shapes in scattered light which are unexplained. The appearance of a disk depends on how its constituent Keplerian ellipses are arranged.…
Light Curves and Colors of the Ejecta from Dimorphos after the DART Impact
Ariel Graykowski, Ryan A. Lambert, Franck Marchis +41
On 26 September 2022 the Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, a satellite of the asteroid 65803 Didymos. Because it is a binary system, it is poss…
Testing the Interaction Between a Substellar Companion and a Debris Disk in the HR 2562 System
Stella Yimiao Zhang, Gaspard Duchêne, Robert J. De Rosa +51
The HR 2562 system is a rare case where a brown dwarf companion resides in a cleared inner hole of a debris disk, offering invaluable opportunities to study the dynamical interacti…
Imaging an 80 AU Radius Dust Ring Around the F5V Star HD 157587
Maxwell A. Millar-Blanchaer, Jason Wang, Paul Kalas +55
We present -band near-infrared polarimetric imaging observations of the F5V star HD~157587 obtained with the Gemini Planet Imager (GPI) that reveal the debris disk as a bright r…
Discovery of a Substellar Companion to the Nearby Debris Disk Host HR 2562
Quinn M. Konopacky, Julien Rameau, Gaspard Duchene +54
We present the discovery of a brown dwarf companion to the debris disk host star HR 2562. This object, discovered with the Gemini Planet Imager (GPI), has a projected separation of…
Gemini Planet Imager Observational Calibrations V: Astrometry and Distortion
Quinn M. Konopacky, Sandrine J. Thomas, Bruce A. Macintosh +24
We present the results of both laboratory and on sky astrometric characterization of the Gemini Planet Imager (GPI). This characterization includes measurement of the pixel scale o…
