Machine-learning clustering of close-in exoplanet populations: links to pebble accretion
Yi Duann, Anders Johansen, Haiyang S. Wang +1
Close-in exoplanets exhibit a wide range of orbital architectures and physical properties shaped by both formation conditions and migration processes. Although population-synthesis…
How stellar mass and disc size shape the formation and migration of super-Earths
Jesper Nielsen, Anders Johansen
The occurrence rate of close-in super-Earths is higher around M-dwarfs compared to stars of higher masses. In this work we aim to understand how the super-Earth population is affec…
On Linking Planet Formation Models, Protoplanetary Disk Properties, and Mature Gas Giant Exoplanet Atmospheres
Adina D. Feinstein, Richard A. Booth, Jennifer B. Bergner +34
Measuring a single elemental ratio (e.g., carbon-to-oxygen) provides insufficient information for understanding the formation mechanisms and evolution that affect our observations…
A primordial radius valley as a consequence of planet formation
Jesper Nielsen, Anders Johansen, Komal Bali +1
The radius distribution of close-in planets has been observed to have a bimodal distribution with a dearth of planets around ~1.5-2.0 commonly referred to as the ''radiu…
