A Clearer View of HAT-P-1 b: JWST NIRSpec G395H Reveals Water, Carbon Dioxide, and Possibly Hydrogen Sulfide

Reza Ashtari, Stephen P. Schmidt, Guangwei Fu +16

As part of JWST's Exoplanet Grand Tour Survey, we use panchromatic transmission spectroscopy to connect HAT-P-1 b's previously studied optical and near-infrared atmosphere to the l…

Revisiting the Atmosphere of HD 149026b: The Role of Stellar Abundances and Choice of Opacities in Exoplanet Atmosphere Modeling

Priyanka Baghel, Jayesh Goyal, Gaurav Shukla

Planet formation occurs within the same molecular cloud as the host star, suggesting a link between the elemental abundances of star and the planet. Exoplanet atmosphere studies of…

A metal-poor atmosphere with a hot interior for a young sub-Neptune progenitor: JWST/NIRSpec transmission spectrum of V1298 Tau b

Saugata Barat, Jean-Michel Désert, Sagnick Mukherjee +19

We present the JWST/NIRSpec G395H transmission spectrum of the young (10 - 20 Myr old) transiting planet V1298 Tau b (9.85+/-0.35 Re, Teq=670K). Combined HST and JWST observations…

X-SHYNE: X-Shooter spectra of young exoplanet analogs II. Presentation and analysis of the full library

Simon Petrus, Gaël Chauvin, Mickaël Bonnefoy +29

The X-SHYNE library is a homogeneous sample of 43 medium-resolution (R=8000) infrared (0.3-2.5um) spectra of young (<500Myr), low-mass (<20Mjup), and cold (Teff=600-2000K) isolated…

WASP-121b's transmission spectrum observed with JWST/NIRSpec G395H reveals thermal dissociation and SiO in the atmosphere

Cyril Gapp, Thomas M. Evans-Soma, Joanna K. Barstow +8

WASP-121b has been established as a benchmark ultrahot Jupiter, serving as a laboratory for the atmospheric chemistry and dynamics of strongly irradiated extrasolar gas giants. Her…

SiO and a super-stellar C/O ratio in the atmosphere of the giant exoplanet WASP-121b

Thomas M. Evans-Soma, David K. Sing, Joanna K. Barstow +15

Refractory elements such as iron, magnesium, and silicon can be detected in the atmospheres of ultrahot giant planets. This provides an opportunity to quantify the amount of refrac…
