Building a habitable earth

Over a period of 6 years, DFG is funding research projects within its SPP framework (DFG-Schwerpunktprogramm) "Building a Habitable Earth". The SPP will contribute to the still open question how Earth became the only known habitable planet.

Members working on this project

We are participating in this collaboration with the project Identifying the origin of Earth's building material: Where do the earth building Planetesimals and Pebbles originate from? A numerical approach of the accretion phase of the earth.

Planetesimal Formation

This graph shows how the number of planetesimals in a protoplanetary disk increases as a function of time. Different curves represent different models where the level of turbulence (α), and the formation efficiency was varied and different drag regimes were considered (St = 1/0 corresponds to Stokes drag considered/not considered). Use the buttons to highlight various parameters.
