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…
