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…
OH/IR stars in the inner Galactic bulge: I. Colour, CO line, and stellar light curve characteristics
H. Olofsson, T. Khouri, S. Muller +11
Stars on the asymptotic giant branch (AGB) play important roles in a number of astronomical contexts. To quantify these roles, it is necessary to establish the mass-loss characteri…
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…
Long-period transiting exoplanets: advances in detection and characterization
Solène Ulmer-Moll, Babatunde Akinsanmi, Simon Müller
Most detected transiting planets have orbits which would fit within the one of Mercury, exposing them to intense stellar irradiation and interactions that significantly alter their…
Deep radiative zones affect giant planet cooling and internal structure: Implications for exoplanet characterisation
Simon Müller, Simon Müller, Ravit Helled
The radiative opacity plays a critical role in shaping the thermal evolution and interior structure of giant planets. Near 2,000 K, a hydrogen-transparency region creates a…
Giant Planet Evolution with MESA
Ravit Helled, Simon Müller, Henrik Knierim
The evolution of gaseous planets is a complex process influenced by various physical parameters and processes. In this study, we present critical modifications to the Modules for E…
