JWST/NIRCam Imaging of Young Stellar Objects. IV. Detailed Imaging of the Protoplanetary Disk around TW Hya
Yu-Chia Lin, Jarron Leisenring, Schuyler G. Wolff +14
As the nearest protoplanetary disk to Earth ( pc), TW Hya is one of the most studied protoplanetary disks and a critical benchmark for testing planet formation theories.…
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…
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…
JWST spectral retrieval of cold directly imaged planet WD0806 b and the first measurement of altitude-dependent K in exoplanet atmospheres
Ben W. P. Lew, Thomas Roellig, Natasha E. Batalha +10
WD0806 b is a rare exoplanet companion orbiting a white dwarf, currently with a projected orbital distance of 2500 au. The Spitzer mid-IR photometry suggests that the temperature i…
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…
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…
