Probing the impact of varied migration and gas accretion rates for the formation of giant planets in the pebble accretion scenario
Nelson Ndugu, Bertram Bitsch, Alessandro Morbidelli +2
The final orbital position of growing planets is determined by their migration speed, which is essentially set by the planetary mass. Small mass planets migrate in type I migration…
The CARMENES search for exoplanets around M dwarfs -- LP 714-47b (TOI 442.01): Populating the Neptune desert
S. Dreizler, I., J. +134
We report the discovery of a Neptune-like planet (LP 714-47 b, P = 4.05204 d, m_b = 30.8 +/- 1.5 M_earth , R_b = 4.7 +/- 0.3 R_earth ) located in the 'hot Neptune desert'. Confirma…
The origins of nearly coplanar, non-resonant systems of close-in super-Earths
Leandro Esteves, André Izidoro, Sean N. Raymond +1
Some systems of close-in "super-Earths" contain five or more planets on non-resonant but compact and nearly coplanar orbits. The Kepler-11 system is an iconic representative of thi…
The solar abundance problem and eMSTOs in clusters
R. Hoppe, M. Bergemann, B. Bitsch +1
We study the impact of accretion from protoplanetary discs on stellar evolution of AFG-type stars. We use a simplified disc model computed using the Two-Pop-Py code that contains t…
Influence of grain growth on the thermal structure of protoplanetary discs
Sofia Savvidou, Bertram Bitsch, Michiel Lambrechts
The thermal structure of a protoplanetary disc is regulated by the opacity that dust grains provide. However, previous works have often considered simplified prescriptions for the…
On the structure and mass delivery towards circumplanetary discs
Matthäus Schulik, Anders Johansen, Bertram Bitsch +2
Circumplanetary discs (CPDs) form around young gas giants and are thought to be the sites of moon formation as well as an intermediate reservoir of gas that feeds the growth of the…
