Searching for Planets Orbiting ~Eridani with JWST/NIRCam
Jorge Llop-Sayson, Charles Beichman, Geoffrey Bryden +10
We present observations of \epseri~with the JWST/NIRCam coronagraph aimed at imaging planets orbiting within this system. In particular, these observations targeted (1) the Jupiter…
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…
JWST/NIRCam Imaging of Young Stellar Objects III: Detailed Imaging of the Nebular Environment Around the HL Tau Disk
Camryn Mullin, Ruobing Dong, Jarron Leisenring +13
As part of the James Webb Space Telescope (JWST) Guaranteed Time Observation (GTO) program "Direct Imaging of YSOs" (program ID 1179), we use JWST NIRCam's direct imaging mode in F…
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…
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…
Searching for Planets Orbiting Fomalhaut with JWST/NIRCam
Marie Ygouf, Charles Beichman, Jorge Llop-Sayson +20
We report observations with the JWST/NIRCam coronagraph of the Fomalhaut system. This nearby A star hosts a complex debris disk system discovered by the IRAS satellite. Observation…
