The compositions of the HR 8799 planets reflect accretion of both solids and metal-enriched gas

Jerry W. Xuan, Jean-Baptiste Ruffio, Yayaati Chachan +24

With four giant planets (, $T_\rm{eff}\sim900-1200$ K) orbiting between 15-70 au, HR 8799 provides an unparalleled testbed for studying giant planet formatio…

Jupiter-like uniform metal enrichment in a system of multiple giant exoplanets

Jean-Baptiste Ruffio, Jerry W. Xuan, Yayaati Chachan +15

The accretion of icy and rocky solids during the formation of a gas giant planet is poorly constrained and challenging to model. Refractory species, like sulfur, are only present i…

Water ice in the debris disk around HD 181327

Chen Xie, Christine H. Chen, Carey M. Lisse +13

Debris disks are exoplanetary systems that contain planets, minor bodies (i.e., asteroids, Kuiper belt objects, comets, etc.), and micron-sized debris dust. Since water ice is the…

HD 143811 AB b: A Directly Imaged Planet Orbiting a Spectroscopic Binary in Sco-Cen

Nathalie K. Jones, Jason J. Wang, Eric L. Nielsen +51

We present confirmation of HD 143811 AB b, a substellar companion to spectroscopic binary HD 143811 AB through direct imaging with the Gemini Planet Imager (GPI) and Keck NIRC2. HD…

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…

Silicate clouds and a circumplanetary disk in the YSES-1 exoplanet system

Kielan K. W. Hoch, Melanie Rowland, Simon Petrus +26

Young exoplanets provide a critical link between understanding planet formation and atmospheric evolution. Direct imaging spectroscopy allows us to infer the properties of young, w…
