GEMS JWST: Hold on to your HATS(-6 b), a sub-solar metallicity giant planet with water, methane and ammonia in its atmosphere
Giannina Guzmán Caloca, Caleb I. Cañas, Nicole L. Wallack +16
HATS-6 b is one of several recently discovered Giant Exoplanets orbiting M-dwarf Stars (GEMS) and is part of a JWST survey that aims to compare bulk and atmospheric properties of t…
Resizing the giants: How modelling adiabatic interiors impacts predicted planetary radii
Simon Müller, Ravit Helled
The interiors of giant planets are commonly assumed to be convective and adiabatic, making the adiabatic temperature gradient a key ingredient in interior and evolution models. Mul…
The evolution and internal structure of Neptunes and sub-Neptunes II. Convective mixing and thermal conductivity
Mark Eberlein, Ravit Helled
Sub-Neptunes and Neptunes are often modeled with distinct, fully convective layers. Yet, there are several arguments for compositions gradients that can inhibit convection. In thes…
Outstanding Questions in Giant Planet Theory
Ravit Helled
Giant planets have key role in shaping planetary systems. Their composition reveals information on the conditions at which planets form, and their interiors serve as natural labora…
Origin and characterization of super-Earths and sub-Neptunes
Léna Parc, Julia Venturini, François Bouchy +6
Super-Earths and sub-Neptunes represent the most common class of exoplanets discovered to date in our galaxy, yet they have no direct analogues in the Solar System. Since 2014, res…
Giant Planet Formation by Disk Instability
Ravit Helled, Oliver Schib, Christian Reinhardt +4
The disk instability (DI) model for giant planet formation remains an attractive alternative in explaining the formation of giant planets at early times, giant planets at large rad…
