Pyrat Bay 2.0: an Upgraded Framework for Exoplanet Atmosphere Modeling in the JWST Era
Patricio E. Cubillos, Jasmina Blecic, Denis Shulyak +1
This article presents a major update to the open-source \textsc{Pyrat Bay} modeling framework (version 2.0), tailored for the characterization of exoplanet atmospheres with the obs…
Phase-curve approach to study atmospheric flows in hot Jupiters
D. Shulyak, W. Dietrich, V. Parmentier +5
Short-orbit gaseous exoplanets are the best targets to study atmospheric dynamics. A time series of emission observations collected at various photometric filters (phase curves) pr…
51 Peg b revisited with VLT/CRIRES+. Constraints on atmospheric thermal structure, chemical composition, and an alternative orbital solution
D. Cont, L. Nortmann, F. Lesjak +18
So far, the atmospheres of non-transiting exoplanets remain poorly explored, and the potential of high-resolution spectroscopy for determining key planetary parameters beyond their…
VLT/CRIRES+ observations of warm Neptune WASP-107 b: Challenges in detecting molecules with ground-based transmission spectroscopy of cooler and cloudy exoplanets
Linn Boldt-Christmas, Adam D. Rains, Nikolai Piskunov +15
Atmospheres of transiting exoplanets can be studied spectroscopically using space-based or ground-based observations. Each has its own strengths and weaknesses, so there are benefi…
Cloudy with a chance of metals: Indications of CO in the atmosphere of GJ 1214 b from high-resolution K-band spectroscopy
L. Nortmann, D. Cont, F. Lesjak +13
Sub-Neptune exoplanets frequently exhibit muted transmission spectra, with GJ 1214 b being the most prominent example. Following years of intense observing campaigns yielding featu…
NLTE atmospheric modelling of the ultra-hot Jupiter WASP-178b and comparison with UV and optical observations
L. Fossati, A. G. Sreejith, T. Koskinen +6
We model the atmosphere of the ultra-hot Jupiter (UHJ) WASP-178b accounting for NLTE effects and compare synthetic transmission spectra with NUV and optical observations. We use th…
