Transmission spectra models including H2O, CH4 and CO of TOI-3362 b (top) and TOI-677 b (bottom) in black with corresponding absorption bands of H2O, CH4 and CO for reference in shades of pink. Top panel: Model spectra of TOI3362 b including absorption of H2O, CH4 and CO. The models assume an isothermal atmosphere at the calculated equilibrium temperature of Teq,A=0 = 1 100 K. The corresponding abundance profiles were computed with FastChem Cond (Stock et al. 2018, 2022; Kitzmann et al. 2023), see Fig. 4, and then translated into mass fractions to produce the transmission models using petitRADTRANS (Mollière et al. 2019). The H2O mass fractions were scaled with factors of 1 (nominal), 10, 100, and 1000 for model injection. Considered absorption bands included in the model to identify the features. The absorption band models were computed under the same assumption, but only including the considered species. Bottom panel: Same as top panel, but for TOI-677 b. The models assume an isothermal atmosphere at the calculated equilibrium temperature of Teq = 1 252 K (Jordán et al. 2020). -- astro-ph.EP

High-resolution Transmission Spectroscopy Of Warm Jupiters: An ESPRESSO Sample With Predictions For ANDES

by Keith CowingJune 14, 2024

Warm Jupiter atmospheres predominantly consist of molecular species, notably water, methane and carbon monoxide, often accompanied by clouds and hazes muting their atmospheric features. In this study, we investigate the […]
