Metallicity and Spectral Evolution of WASP-39 b: The Limited Role of Hydrodynamic Escape
Amy J. Louca, Yamila Miguel, Daria Kubyshkina
The recent observations on WASP-39 b by JWST have revealed hints of high metallicity within the atmosphere compared to its host star (Feinstein et al. 2022; Ahrer et al. 2023; Alde…
Exoplanet Interior Retrievals: core masses and metallicities from atmospheric abundances
Sanne Bloot, Yamila Miguel, Michaël Bazot +1
The mass and distribution of metals in the interiors of exoplanets are essential for constraining their formation and evolution processes. Nevertheless, with only masses and radii…
Using a neural network approach to accelerate disequilibrium chemistry calculations in exoplanet atmospheres
Julius L. A. M. Hendrix, Amy J. Louca, Yamila Miguel
In this era of exoplanet characterisation with JWST, the need for a fast implementation of classical forward models to understand the chemical and physical processes in exoplanet a…
The MUSCLES Extension for Atmospheric and Transmission Spectroscopy: UV and X-ray Host-star Observations for JWST ERS & GTO Targets
Patrick R. Behr, Kevin France, Alexander Brown +8
X-ray through infrared spectral energy distributions (SEDs) are essential for understanding a star's effect on exoplanet atmospheric composition and evolution. We present a catalog…
Retrieval survey of metals in six ultra-hot Jupiters: Trends in chemistry, rain-out, ionisation and atmospheric dynamics
Siddharth Gandhi, Aurora Kesseli, Yapeng Zhang +9
Ground-based high-resolution spectroscopy (HRS) has detected numerous chemical species and atmospheric dynamics in exoplanets, most notably ultra-hot Jupiters (UHJs). However, quan…
An extreme test case for planet formation: a close-in Neptune orbiting an ultracool star
Gudmundur Stefansson, Suvrath Mahadevan, Yamila Miguel +27
In current theories of planet formation, close-orbiting planets as massive as Neptune are expected to be very rare around low-mass stars. We report the discovery of a Neptune-mass…
The energetic particle environment of a GJ 436 b-like planet
D. Rodgers-Lee, P. B. Rimmer, A. A. Vidotto +8
A key first step to constrain the impact of energetic particles in exoplanet atmospheres is to detect the chemical signature of ionisation due to stellar energetic particles and Ga…
Jupiter's interior from Juno: Equation-of-state uncertainties and dilute core extent
S. Howard, T. Guillot, M. Bazot +10
The Juno mission has provided measurements of Jupiter s gravity field with an outstanding level of accuracy, leading to better constraints on the interior of the planet. Improving…
Interior and Evolution of the Giant Planets
Yamila Miguel, Allona Vazan
The giant planets were the first to form and hold the key to unveiling the solar system's formation history in their interiors and atmospheres. Furthermore, the unique conditions p…
Observability of silicates in volatile atmospheres of super-Earths and sub-Neptunes
Mantas Zilinskas, Yamila Miguel, Chritstiaan P. A. van Buchem +1
Many of the confirmed short period super-Earths and smaller sub-Neptunes are sufficiently irradiated for the surface silicates to be sustained in a long-lasting molten state. While…
