Clouds form on the hot Saturn JWST ERO target WASP-96b

D. Samra et al.

Summary: This study explores the cloud formation in the atmosphere of the hot Saturn exoplanet WASP-96b. The results show that clouds are common throughout the atmosphere, and they have an impact on the observations made by NIRISS and NIRSpec. The MIRI instrument may reveal atmospheric asymmetries between the limbs of the terminator on WASP-96b.

Solar-to-supersolar sodium and oxygen absolute abundances for a 'hot Saturn' orbiting a metal-rich star

Nikolay K. Nikolov et al.

Summary: We present new analysis of infrared transmission spectroscopy of the cloud-free hot-Saturn WASP-96b performed with the Hubble and Spitzer Space Telescopes (HST and Spitzer). The WASP-96b spectrum exhibits the absorption feature from water in excellent agreement with synthetic spectra computed assuming a cloud-free atmosphere. The HST-Spitzer spectrum is coupled with Very Large Telescope (VLT) optical transmission spectroscopy which reveals the full pressure-broadened profile of the sodium absorption feature and enables the derivation of absolute abundances.

The ExoMolOP database: Cross sections and k-tables for molecules of interest in high-temperature exoplanet atmospheres

Katy L. Chubb et al.

Summary: The ExoMolOP database contains opacity data for over 80 species of molecules of astrophysical interest, suitable for characterizing high-temperature exoplanets or cool stellar and substellar atmospheres. The data are formatted in different ways for different exoplanet atmosphere retrieval codes.

The First Retrieval of a Substellar Subdwarf: A Cloud-free SDSS J125637.13-022452.4

Eileen C. Gonzales et al.

Summary: The study presents the first retrieval analysis of SDSS J1256-0224, a substellar subdwarf, using the Brewster retrieval code base. The best-fit model for SDSS J1256-0224 is a cloud-free model with an ion abundance corresponding to [Fe/H](ion) = -1.5, but it is indistinguishable from other cloud-free models due to the assumption of subsolar carbon-to-oxygen ratio. Additionally, the study is able to constrain abundances for H2O, FeH, and CrH, but not for carbon-bearing species, likely due to the low metallicity of SDSS J1256-0224.
