Why heterogeneous cloud particles matter: Iron-bearing species and cloud particle morphology affects exoplanet transmission spectra
Sven Kiefer, Dominic Samra, David A. Lewis +5
The possibility of observing spectral features in exoplanet atmospheres with space missions like JWST and ARIEL necessitates the accurate modelling of cloud particle opacities. In…
Inhomogeneous terminators on the exoplanet WASP-39 b
Néstor Espinoza, Maria E. Steinrueck, James Kirk +40
Transmission spectroscopy has been a workhorse technique over the past two decades to constrain the physical and chemical properties of exoplanet atmospheres. One of its classical…
A grid of self-consistent MSG (MARCS-StaticWeather-GGchem) cool stellar, sub-stellar, and exoplanetary model atmospheres
Uffe G. Jørgensen, Flavia Amadio, Beatriz Campos Estrada +8
Computation of a grid of self consistent 1D model atmospheres of cool stars, sub-stellar objects and exoplanets in the effective temperature range 300K to 3000K, including cloud fo…
A formation pathway for terrestrial planets with moderate water content involving atmospheric-volatile recycling
Jonas Müller, Bertram Bitsch, Aaron David Schneider
Of the many recently discovered terrestrial exoplanets, some are expected to harbor moderate water mass fractions of a few percent. The formation pathways that can produce planets…
Examining the detectability of ringing on highly eccentric exoplanets
Mathijs Vanrespaille, Robin Baeyens, Aaron David Schneider +2
Eccentric exoplanets offer an opportunity to study the response of an atmosphere to changing thermal forcing and the robustness of the super-rotating equatorial jet seen on tidally…
Nightside clouds and disequilibrium chemistry on the hot Jupiter WASP-43b
Taylor J. Bell, Nicolas Crouzet, Patricio E. Cubillos +80
Hot Jupiters are among the best-studied exoplanets, but it is still poorly understood how their chemical composition and cloud properties vary with longitude. Theoretical models pr…
chemcomp: Modeling the chemical composition of planets formed in protoplanetary disks
Aaron David Schneider, Bertram Bitsch
Future observations of exoplanets will hopefully reveal detailed constraints on planetary compositions. Recently, we have developed and introduced chemcomp (Schneider & Bitsch 2021…
Harnessing machine learning for accurate treatment of overlapping opacity species in general circulation models
Aaron David Schneider, Paul Mollière, Gilles Louppe +4
To understand high precision observations of exoplanets and brown dwarfs, we need detailed and complex general circulation models (GCMs) that incorporate hydrodynamics, chemistry,…
Constraining the formation history of the HAT-P-11 system by atmospheric abundances
Lena Chatziastros, Bertram Bitsch, Aaron David Schneider
The chemical fingerprint of a planet reveals information about its formation history regarding when and where it formed. The water content of a planet can help to constrain its for…
Photodissociation and induced chemical asymmetries on ultra-hot gas giants. A case study of HCN on WASP-76 b
Robin Baeyens, Jean-Michel Désert, Annemieke Petrignani +2
Recent observations have resulted in the detection of chemical gradients on ultra-hot gas giants. Notwithstanding their high temperature, chemical reactions in ultra-hot atmosphere…
Evidence of Radius Inflation in Radiative GCM Models of WASP-76b due to the Advection of Potential Temperature
Felix Sainsbury-Martinez, Pascal Tremblin, Aaron David Schneider +6
Understanding the discrepancy between the radii of observed hot Jupiters and standard 'radiative-convective' models remains a hotly debated topic in the exoplanet community. One me…
WASP-39b: exo-Saturn with patchy cloud composition, moderate metallicity, and underdepleted S/O
Ludmila Carone, David A. Lewis, Dominic Samra +2
WASP-39b is one of the first extrasolar giant gas planets that has been observed within the JWST ERS program. Fundamental properties that may enable the link to exoplanet formation…
Clouds form on the hot Saturn JWST ERO target WASP-96b
