Searching for Planets Orbiting Vega with the James Webb Space Telescope
Charles Beichman, Geoffrey Bryden, Jorge Llop-Sayson +15
The most prominent of the IRAS debris disk systems, Lyrae (Vega), at a distance of 7.7 pc, has been observed by both the NIRCam and MIRI instruments on the James Webb Space Tel…
JWST/NIRCam Detection of the Fomalhaut C Debris Disk in Scattered Light
Kellen Lawson, Joshua E. Schlieder, Jarron M. Leisenring +20
Observations of debris disks offer important insights into the formation and evolution of planetary systems. Though M dwarfs make up approximately 80% of nearby stars, very few M-d…
High-precision atmospheric characterization of a Y dwarf with JWST NIRSpec G395H spectroscopy: isotopologue, C/O ratio, metallicity, and the abundances of six molecular species
Ben W. P. Lew, Thomas Roellig, Natasha E. Batalha +19
The launch of the James Webb Space Telescope (JWST) marks a pivotal moment for precise atmospheric characterization of Y dwarfs, the coldest brown dwarf spectral type. In this stud…
High-Precision Atmospheric Constraints for a Cool T Dwarf from JWST Spectroscopy
Callie E. Hood, Sagnick Mukherjee, Jonathan J. Fortney +12
We present observations of the T8 dwarf 2MASS 0415-0935 with JWST's NIRSpec spectrograph using the G395H grating ( 2.87 - 5.14 m). We perform the first atmospheric retriev…
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…
JWST/NIRCam Imaging of Young Stellar Objects. I. Constraints on Planets Exterior to The Spiral Disk Around MWC 758
Kevin Wagner, Jarron Leisenring, Gabriele Cugno +18
MWC 758 is a young star hosting a spiral protoplanetary disk. The spirals are likely companion-driven, and two previously-identified candidate companions have been identified -- on…
