Phase-dependent chemistry of WASP-43 b revealed with a suite of one-, two-, and three-dimensional models

Robin Baeyens, Julianne I. Moses, Jasmina Blecic +17

Our goal is to investigate the chemistry of the hot Jupiter WASP-43 b in detail using theoretical models, considering the constraints of the James Webb Space Telescope MIRI phase c…

Limb Asymmetries on WASP-39b: A Multi-GCM Comparison of Chemistry, Clouds, and Hazes

Maria E. Steinrueck, Arjun B. Savel, Duncan A. Christie +27

With JWST, observing separate spectra of the morning and evening limbs of hot Jupiters has finally become a reality. The first such observation was reported for WASP-39b, where the…

Reliability of 1D radiative-convective photochemical-equilibrium retrievals on transit spectra of WASP-107b

Thomas Konings, Linus Heinke, Robin Baeyens +3

Observations of WASP-107b suggest a metal-rich and carbon-deprived atmosphere with an extremely hot interior based on detections of SO, HO, CO, CO, NH, and CH.…

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…

DARWEN: Data-driven Algorithm for Reduction of Wide Exoplanetary Networks

A. Lira-Barria, J. N. Harvey, T. Konings +5

Exoplanet atmospheric modeling is advancing from chemically diverse one-dimensional (1D) models to three-dimensional (3D) global circulation models (GCMs), which are crucial for in…

First Comparative Exoplanetology Within a Transiting Multi-planet System: Comparing the atmospheres of V1298 Tau b and c

Saugata Barat, Jean-Michel Désert, Jayesh M. Goyal +13

The V1298 Tau system (20-30Myr), is a benchmark young multi-planet system that provides the opportunity to perform comparative exoplanetology between planets orbiting the same star…
