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 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…
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…
First Observations of the Brown Dwarf HD 19467 B with JWST
Alexandra Z. Greenbaum, Jorge Llop-Sayson, Ben Lew +21
We observed HD 19467 B with JWST's NIRCam in six filters spanning 2.5-4.6 with the Long Wavelength Bar coronagraph. The brown dwarf HD 19467 B was initially identified through…
JWST NIRCam Defocused Imaging: Photometric Stability Performance and How it Can Sense Mirror Tilts
Everett Schlawin, Thomas Beatty, Brian Brooks +25
We use JWST NIRCam short wavelength photometry to capture a transit lightcurve of the exoplanet HAT-P-14 b to assess performance as part of instrument commissioning. The short wave…
JWST/NIRCam Coronagraphy: Commissioning and First On-Sky Results
Julien H. Girard, Jarron Leisenring, Jens Kammerer +53
In a cold and stable space environment, the James Webb Space Telescope (JWST or "Webb") reaches unprecedented sensitivities at wavelengths beyond 2 microns, serving most fields of…
First Peek with JWST/NIRCam Wide-Field Slitless Spectroscopy: Serendipitous Discovery of a Strong [O III]/H Emitter at
Fengwu Sun, Eiichi Egami, Nor Pirzkal +15
We report the serendipitous discovery of an [O III] 4959/5007 and H line emitter in the Epoch of Reionization (EoR) with the JWST commissioning data taken in the NIRCam wide…
The conceptual design of GMagAO-X: visible wavelength high contrast imaging with GMT
Jared R. Males, Laird M. Close, Sebastiaan Y. Haffert +10
We present the conceptual design of GMagAO-X, an extreme adaptive optics system for the 25 m Giant Magellan Telescope (GMT). We are developing GMagAO-X to be available at or shortl…
The Science Performance of JWST as Characterized in Commissioning
Jane Rigby, Marshall Perrin, Michael McElwain +623
This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performanc…
Two NIRCam channels are Better than One: How JWST Can Do More Science with NIRCam's Short-Wavelength Dispersed Hartmann Sensor
Everett Schlawin, Marcia Rieke, Jarron Leisenring +8
The James Webb Space Telescope (JWST) offers unprecedented sensitivity, stability, and wavelength coverage for transiting exoplanet studies, opening up new avenues for measuring at…
