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…

Two-Dimensional Eclipse Mapping of the Hot Jupiter WASP-43b with JWST MIRI/LRS

Mark Hammond, Taylor J. Bell, Ryan C. Challener +21

We present eclipse maps of the two-dimensional thermal emission from the dayside of the hot Jupiter WASP-43b, derived from an observation of a phase curve with the JWST MIRI/LRS in…

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…

Modelling reflected polarised light from close-in giant exoplanet WASP-96b using PolHEx (Polarisation of Hot Exoplanets)

Katy L. Chubb, Daphne M. Stam, Christiane Helling +2

We present the Polarisation of Hot Exoplanets (PolHEx) code for modelling the total flux (F) and degree of linear polarisation (P) of light spectra reflected by close-in, tidally l…

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…

Cloud property trends in hot and ultra-hot giant gas planets (WASP-43b, WASP-103b, WASP-121b, HAT-P-7b, and WASP-18b)

Ch. Helling, D. Lewis, D. Samra +8

Ultra-hot Jupiters are the hottest exoplanets discovered so far. Observations begin to provide insight into the composition of their extended atmospheres and their chemical day/nig…

The ARCiS framework for Exoplanet Atmospheres: Modelling Philosophy and Retrieval

Michiel Min, Chris W. Ormel, Katy Chubb +2

Aims: ARCiS, a novel code for the analysis of exoplanet transmission and emission spectra is presented. The aim of the modelling framework is to provide a tool able to link observa…

Mineral cloud and hydrocarbon haze particles in the atmosphere of the hot Jupiter JWST target WASP-43b

Ch. Helling, Y. Kawashima, V. Graham +5

Having a short orbital period and being tidally locked makes WASP-43b an ideal candidate for JWST observations. Phase curve observations of an entire orbit will enable the mapping…

Aluminium oxide in the atmosphere of hot Jupiter WASP-43b

Katy L. Chubb, Michiel Min, Yui Kawashima +2

We have conducted a re-analysis of publicly available Hubble Space Telescope Wide Field Camera 3 (HST WFC3) transmission data for the hot-Jupiter exoplanet WASP-43b, using the Baye…

Mineral snowflakes on exoplanets and brown dwarfs: Effects of micro-porosity, size distributions, and particle shape

Dominic Samra, Christiane Helling, Michiel Min

Exoplanet atmosphere characterisation has become an important tool in understanding exoplanet formation, evolution. However, clouds remain a key challenge for characterisation: upc…

Understanding the atmospheric properties and chemical composition of the ultra-hot Jupiter HAT-P-7b II. Mapping the effects of gas kinetics

Karan Molaverdikhani, Christiane Helling, Ben W. P. Lew +5

The atmospheres of ultra-hot Jupiters are commonly considered to be at thermochemical equilibrium. We aim to provide disequilibrium chemistry maps for a global understanding of the…

Understanding the atmospheric properties and chemical composition of the ultra-hot Jupiter HAT-P-7b: I. Cloud and chemistry mapping

Ch. Helling, N. Iro, L. Corrales +10

Ultra-hot Jupiters have recently attracted interest from observers and theoreticians alike, as they provide observationally accessible test cases. We apply a hierarchical modelling…
