Key to rapid planet formation

- EN - DE

In young planetary systems, gas giants form more efficiently and faster than previously assumed as shown by new computer simulations.

Ring-shaped perturbations in disks of gas and dust orbiting young stars can trigger the formation of several gas giants, as researchers from the ORIGINS Cluster of Excellence, Ludwig-Maximilians-Universität in Munich and the Max Planck Institute for Solar System Research (MPS) in Göttingen report in the current issue of the journal Astronomy and Astrophysics. The team has developed a model that for the first time combines all the necessary physical processes that play a role in planet formation. According to this model, giant planets can form more efficiently and faster than previously assumed. ...
