Harnessing machine learning for accurate treatment of overlapping opacity species in general circulation models

1 code implementation1 Nov 2023 Aaron David Schneider, Paul Mollière, Gilles Louppe, Ludmila Carone, Uffe Gråe Jørgensen, Leen Decin, Christiane Helling

For this study, we specifically examined the coupling between chemistry and radiation in GCMs and compared different methods for the mixing of opacities of different chemical species in the correlated-k assumption, when equilibrium chemistry cannot be assumed.

Indications for very high metallicity and absence of methane for the eccentric exo-Saturn WASP-117b

no code implementations9 Jun 2020 Ludmila Carone, Paul Mollière, Yifan Zhou, Jeroen Bouwman, Fei Yan, Robin Baeyens, Dániel Apai, Nestor Espinoza, Benjamin V. Rackham, Andrés Jordán, Daniel Angerhausen, Leen Decin, Monika Lendl, Olivia Venot, Thomas Henning

Using a 1D atmosphere model with isothermal temperature, uniform cloud deck and equilibrium chemistry, the Bayesian evidence of a retrieval analysis of the transmission spectrum indicates a preference for a high atmospheric metallicity ${\rm [Fe/H]}=2. 58^{+0. 26}_{-0. 37}$ and clear skies.

MIRACLES: atmospheric characterization of directly imaged planets and substellar companions at 4-5 micron. I. Photometric analysis of $β$ Pic b, HIP 65426 b, PZ Tel B and HD 206893 B

The $L'$-NB4. 05 and $L'$-$M'$ colors of the studied sample are all red while the NB4. 05-$M'$ color is blue for $\beta$ Pic b, gray for PZ Tel B, and red for HIP 65426 b and HD 206893 B (although typically with low significance).

Polarized scattered light from self-luminous exoplanets. Three-dimensional scattering radiative transfer with ARTES

1 code implementation28 Jun 2017 Tomas Stolker, Michiel Min, Daphne M. Stam, Paul Mollière, Carsten Dominik, Rens Waters

The code is applicable to calculations of reflected light and thermal radiation in a spherical grid with a parameterized distribution of gas, clouds, hazes, and circumplanetary material.
