Influence of sub- and super-solar metallicities on the compositions of solid planetary building blocks
Bertram Bitsch, Chiara Battistini
The composition of the protoplanetary disc is linked to the composition of the host star, where a higher overall metallicity of the host star provides more building blocks for plan…
Exploring the conditions for forming cold gas giants through planetesimal accretion
Anders Johansen, Bertram Bitsch
The formation of cold gas giants similar to Jupiter and Saturn in orbit and mass is a great challenge for planetesimal-driven core accretion models because the core growth rates fa…
Planet formation and migration near the silicate sublimation front in protoplanetary disks
Mario Flock, Neal J. Turner, Gijs D. Mulders +3
The increasing number of newly detected exoplanets at short orbital periods raises questions about their formation and migration histories. A particular puzzle that requires explan…
Global 3D radiation-hydrodynamic simulations of gas accretion: The opacity dependent growth of Saturn-mass planets
Matthäus Schulik, Anders Johansen, Bertram Bitsch +1
The full spatial structure and temporal evolution of the accretion flow into the envelopes of growing gas giants in their nascent discs is only accessible in simulations. Such simu…
Inner rocky super-Earth formation: distinguishing the formation pathways in viscously heated and passive discs
Bertram Bitsch
The formation of super-Earths is strongly linked to the structure of the protoplanetary disc, which determines growth and migration. In the pebble accretion scenario, planets grow…
Are the observed gaps in protoplanetary discs caused by growing planets?
Nelson Ndugu, Bertram Bitsch, Edward Jurua
Recent detailed observations of protoplanetary discs revealed a lot of sub-structures which are mostly ring-like. One interpretation is that these rings are caused by growing plane…
