GRaTer-JAX: An Accelerated Package for Debris Disk Modeling
Mihir Kondapalli, Briley L. Lewis, Jaren N. Ashcraft +1
GRaTer-JAX is a Python package for modeling debris disks, disks of dust around stars that pro- vide important clues about the formation, structure, and evolution of planetary syste…
JWST NIRCam Reveals the Largest Known M-dwarf Debris Disk Around TWA 10 and New Scattered-Light Observations of the TWA 25 Debris Disk
Katie A. Crotts, Aarynn L. Carter, Beth Biller +26
We present JWST NIRCam observations of two M-dwarf systems located in the TW Hydra association, TWA 10 and TWA 25. Both systems harbor detected debris disks in the F200W and F444W…
Discovery of a Debris Disk Around TWA 20
Skyler Palatnick, Maxwell A. Millar-Blanchaer, Jingwen Zhang +20
We report the discovery of a debris disk surrounding the M3 star, TWA 20, revealed by JWST coronagraphic observations using the Near-infrared Camera (NIRCam). With reference-star d…
Characterization of the Host Binary of the Directly Imaged Exoplanet HD 143811 AB b
Anne E. Peck, William Roberson, Eric L. Nielsen +50
HD~143811~AB is the host star to the directly imaged planet HD~143811~AB~b, which was recently discovered using data from the Gemini Planet Imager and Keck NIRC2. A member of the S…
The Keck-HGCA Pilot Survey II: Direct Imaging Discovery of HD 63754 B, a ~20 au Massive Companion Near the Hydrogen Burning Limit
Yiting Li, Timothy D. Brandt, Kyle Franson +15
We present the joint astrometric and direct imaging discovery, mass measurement, and orbital analysis of HD 63754 B (HIP 38216 B), a companion near the stellar-substellar boundary…
Subaru/CHARIS High-Resolution Mode Spectroscopy of the Brown Dwarf Companion HD 33632 Ab
Aidan Gibbs, Briley Lewis, Michael Fitzgerald +6
Brown dwarfs (BD) are model degenerate in age and mass. High-contrast imaging and spectroscopy of BD companions to host stars where the mass and age can be independently constraine…
Gemini Planet Imager Observations of a Resolved Low-Inclination Debris Disk Around HD 156623
Briley L. Lewis, Michael P. Fitzgerald, Thomas M. Esposito +12
The 16 Myr-old A0V star HD 156623 in the Scorpius--Centaurus association hosts a high-fractional-luminosity debris disk, recently resolved in scattered light for the first time by…
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…
