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…
Deep radiative zones affect giant planet cooling and internal structure: Implications for exoplanet characterisation
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…
TOI-2374 b and TOI-3071 b: two metal-rich sub-Saturns well within the Neptunian desert
Alejandro Hacker, Rodrigo F. Díaz, David J. Armstrong +40
We report the discovery of two transiting planets detected by the Transiting Exoplanet Survey Satellite (TESS), TOI-2374 b and TOI-3071 b, orbiting a K5V and an F8V star, respectiv…
Discovery of a cold giant planet and mass measurement of a hot super-Earth in the multi-planetary system WASP-132
N. Grieves, F. Bouchy, D. J. Armstrong +25
Hot Jupiters generally do not have nearby planet companions, as they may have cleared out other planets during their inward migration from more distant orbits. This gives evidence…
Can Jupiter's atmospheric metallicity be different from the deep interior?
Simon Müller, Ravit Helled
Updated formation and structure models of Jupiter predict a metal-poor envelope. This is at odds with the two to three times solar metallicity measured by the Galileo probe. Additi…
Searching for Giant Exoplanets around M-dwarf Stars (GEMS) I: Survey Motivation
Shubham Kanodia, Caleb I. Cañas, Suvrath Mahadevan +13
Recent discoveries of transiting giant exoplanets around M-dwarf stars (GEMS), aided by the all-sky coverage of TESS, are starting to stretch theories of planet formation through t…
