The James Webb Space Telescope Mission
Jonathan P. Gardner, John C. Mather, Randy Abbott +1004
Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized…
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 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…
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…
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 Observations of the Enigmatic Y Dwarf WISE 1828+2650: I. Limits to a Binary Companion
Matthew De Furio, Ben W. Lew, Charles A. Beichman +20
The Y-dwarf WISE 1828+2650 is one of the coldest known Brown Dwarfs with an effective temperature of 300 K. Located at a distance of just 10 pc, previous model-based estimate…
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…
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 Te…
