About this group
The planet formation group at the Institute for Theoretical Astrophysics was founded in November 2010. The group studies how planets and exoplanets are formed from cosmic dust in protoplanetary disk. We do this with numerical modeling, focusing on:
- The structure, the formation and the evolution of planetary birthplaces (protoplanetary disks)
- The coagulation, fragmentation and motion of dust aggregates in these disks
- The formation of planetesimals (i.e. 1-100 km-size bodies such as comets and asteroids)
- The runaway and oligarchic growth of planetary embryos out of swarms of planetesimals
- The N-body interactions between newly formed planets.
