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…

Gemini Planet Imager Spectroscopy of the Dusty Substellar Companion HD 206893 B

K. Ward-Duong, J. Patience, K. Follette +55

We present new near-infrared Gemini Planet Imager (GPI) spectroscopy of HD 206893 B, a substellar companion orbiting within the debris disk of its F5V star. The , , , 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…
