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…

The mass-radius relation of exoplanets, revisited

Simon Müller, Jana Baron, Ravit Helled +2

Determining the mass-radius (-) relation of exoplanets is important for exoplanet characterization. Here we present a re-analysis of the - relations and their transitio…

An extended low-density atmosphere around the Jupiter-sized planet WASP-193 b

Khalid Barkaoui, Francisco J. Pozuelos, Coel Hellier +32

Gas giants transiting bright nearby stars provide crucial insights into planetary system formation and evolution mechanisms. Most of these planets exhibit certain average character…

Warm giant exoplanet characterisation: current state, challenges and outlook

Simon Müller, Ravit Helled

The characterisation of giant exoplanets is crucial to constrain giant planet formation and evolution theory and for putting the solar-system's giant planets in perspective. Typica…

Towards a new era in giant exoplanet characterisation

Simon Müller, Ravit Helled

Determining the composition of giant exoplanets is crucial for understanding their origin and evolution. However, the planetary bulk composition is not measured directly but must b…

On the diversity in mass and orbital radius of giant planets formed via disk instability

Simon Müller, Ravit Helled, Lucio Mayer

We present a semi-analytical population synthesis model of protoplanetary clumps formed by disk instability at radial distances of 80 - 120 AU. Various clump density profiles, init…
