Constraining planet formation based on the atmospheric composition of exoplanets is a
fundamental goal of the exoplanet community. Existing studies commonly try to constrain …

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. Typically …

Recent observations of extrasolar gas giants suggest super-stellar C/O ratios in planetary
atmospheres, while interior models of observed extrasolar giant planets additionally suggest …

Relating planet formation to atmospheric composition has been a long-standing goal of the
planetary science community. So far, most modeling studies have focused on predicting the …

AF Lep A+ b is a remarkable planetary system hosting a gas-giant planet that has the lowest
dynamical mass among directly imaged exoplanets. We present an in-depth analysis of the …

We report the discovery of TOI-2180 b, a 2.8 MJ giant planet orbiting a slightly evolved G5
host star. This planet transited only once in Cycle 2 of the primary Transiting Exoplanet …

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

Observations of the population of cold Jupiter planets (r> 1 AU) show that nearly all of these
planets orbit their host star on eccentric orbits. For planets up to a few Jupiter masses …

Giant exoplanets seem to have on average a much higher heavy-element content than the
Solar System giants. Past attempts to explain this heavy-element content include collisions …

Planet engulfment can be inferred from enhancement of refractory elements in the
photosphere of the engulfing star following accretion of rocky planetary material. Such …
