A Uniform Analysis of Debris Disks with the Gemini Planet Imager II: Constraints on Dust Density Distribution Using Empirically-Informed Scattering Phase Functions
Justin Hom, Jennifer Patience, Christine H. Chen +40
Spatially-resolved images of debris disks are necessary to determine disk morphological properties and the scattering phase function (SPF) which quantifies the brightness of scatte…
A Uniform Analysis of Debris Disks with the Gemini Planet Imager I: An Empirical Search for Perturbations from Planetary Companions in Polarized Light Images
Katie A. Crotts, Brenda C. Matthews, Gaspard Duchêne +37
The Gemini Planet Imager (GPI) has excelled in imaging debris disks in the near-infrared. The GPI Exoplanet Survey (GPIES) imaged twenty-four debris disks in polarized -band lig…
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…
