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…

The Outflow of the B335 Protostar II: After the Outburst

Klaus W. Hodapp, Adwin Boogert, Doug Johnstone +6

The B335 protostar has recently undergone a major, still ongoing, outburst detected in scattered light from its outflow cavity, offering a rare opportunity to study its impact on a…

Unveiling two deeply embedded young protostars in the S68N Class 0 protostellar core with JWST/NIRSpec

Valentin J. M. Le Gouellec, Ben W. P. Lew, Thomas P. Greene +11

The near-infrared (NIR) emission of the youngest protostars still needs to be characterized to better understand the evolution of their accretion and ejection activity. We analyze…

Transit Spectroscopy of K2-33b with Subaru/IRD: Spin-Orbit Alignment and Tentative Atmospheric Helium

Teruyuki Hirano, Eric Gaidos, Hiroki Harakawa +13

Exoplanets in their infancy are ideal targets to probe the formation and evolution history of planetary systems, including the planet migration and atmospheric evolution and dissip…

The outflow of the protostar in B335: I

Klaus W. Hodapp, Laurie L. Chu, Thomas Greene +10

The isolated globule B335 contains a single, low luminosity Class 0 protostar associated with a bipolar nebula and outflow system seen nearly perpendicular to its axis. We observed…

JWST/NIRCam Imaging of Young Stellar Objects. II. Deep Constraints on Giant Planets and a Planet Candidate Outside of the Spiral Disk Around SAO 206462

Gabriele Cugno, Jarron Leisenring, Kevin R. Wagner +17

We present JWST/NIRCam F187N, F200W, F405N and F410M direct imaging data of the disk surrounding SAO 206462. Previous images show a very structured disk, with a pair of spiral arms…
