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…

Low-mass members of nearby young stellar moving groups from Gaia EDR3

Jinhee Lee, Inseok Song, Simon J. Murphy

Gaia EDR3 offers greatly improved kinematics for nearby objects, including members of nearby young stellar moving groups (NYMGs). In this study, we aim to identify low-mass NYMG me…

V488 Per revisited: no strong mid-infrared emission features and no evidence for stellar/sub-stellar companions

Swetha Sankar, Carl Melis, Beth L. Klein +4

We present characterization of the planetary system architecture for V488 Per, the dustiest main sequence star known with a fractional infrared luminosity of ~16%. Far-infrared ima…

Highly structured inner planetary system debris around the intermediate age Sun-like star TYC 8830 410 1

Carl Melis, Johan Olofsson, Inseok Song +4

We present detailed characterization of the extremely dusty main sequence star TYC 8830 410 1. This system hosts inner planetary system dust (Tdust~300 K) with a fractional infrare…

Multiband Polarimetric Imaging of HR 4796A with the Gemini Planet Imager

Pauline Arriaga, Michael P. Fitzgerald, Gaspard Duchêne +49

HR4796A hosts a well-studied debris disk with a long history due to its high fractional luminosity and favorable inclination lending itself well to both unresolved and resolved obs…

The Gemini Planet Imager view of the HD 32297 debris disk

Gaspard Duchene, Malena Rice, Justin Hom +60

We present new -band scattered light images of the HD 32297 edge-on debris disk obtained with the Gemini Planet Imager (GPI). The disk is detected in total and polarized intensi…
