JWST-TST DREAMS: A Super-Solar Metallicity in WASP-17 b Dayside Atmosphere from NIRISS SOSS Eclipse Spectroscopy

Amélie Gressier, Ryan J. MacDonald, Néstor Espinoza +26

We present the first emission spectrum of the hot Jupiter WASP-17 b using one eclipse observation from the JWST Near Infrared Imager and Slitless Spectrograph (NIRISS) Single Objec…

MIRI MRS Observations of Beta Pictoris II. The Spectroscopic Case for a Recent Giant Collision

Christine H. Chen, Cicero X. Lu, Kadin Worthen +17

Modeling observations of the archetypal debris disk around Pic, obtained in 2023 January with the MIRI MRS on board JWST, reveals significant differences compared with that obt…

JWST-TST High Contrast: JWST/NIRCam observations of the young giant planet Pic b

Jens Kammerer, Kellen Lawson, Marshall D. Perrin +14

We present the first JWST/NIRCam observations of the directly-imaged gas giant exoplanet Pic b. Observations in six filters using NIRCam's round coronagraphic masks provide a h…

The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems V: Do Self-Consistent Atmospheric Models Represent JWST Spectra? A Showcase With VHS 1256 b

Simon Petrus, Niall Whiteford, Polychronis Patapis +119

The unprecedented medium-resolution (R~1500-3500) near- and mid-infrared (1-18um) spectrum provided by JWST for the young (140+/-20Myr) low-mass (12-20MJup) L-T transition (L7) com…

MIRI MRS Observations of Beta Pictoris I. The Inner Dust, the Planet, and the Gas

Kadin Worthen, Christine H. Chen, David R. Law +15

We present JWST MIRI Medium Resolution Spectrograph (MRS) observations of the Pictoris system. We detect an infrared excess from the central unresolved point source from 5 to 7…
