Temperature isosurfaces from a 3D simulation of thermal convection in Mars’ mantle. How does the early evolution of the mantle and atmosphere influence the present conditions status of the interior of a planet?
We invite applications for one PhD position at the Institute for Planetary Research (Department of Planetary Physics) of the German Aerospace Center (DLR) in Berlin. The position is jointly funded by the DLR and the Helmholtz Association (HGF) in the framework of the newly established Helmholtz Young Investigator Group Early Dynamics of the Terrestrial Planets and Role of the Biosphere on their Evolution. The project, which will be carried out in cooperation with the Center for Astronomy and Astrophysics of the Technische Universität Berlin (TUB), aims at investigating the conditions of the surface and interior of the terrestrial planets shortly after their formation and how these have influenced the subsequent planetary evolution.
Research topic: Magma ocean solidification in interaction with the atmosphere
Kinetic energy from large impactors and gravitational potential energy released upon core formation can melt a large portion of a planet’s mantle leading to the formation of deep magma oceans. Degassing of volatiles upon solidification of the magma ocean affects the composition of the primordial atmosphere, whose presence buffers heat escape and dictates the time-scale for mantle cooling and crystallization. The successful candidate will develop a thermo-chemical model of magma ocean solidification and degassing, and couple it with atmospheric models of radiative-convective equilibrium with the goal of understanding the primitive thermal and chemical conditions occurring on the surface and in the mantle of the terrestrial planets, and how these influence the later evolution of the surface and of the interior.
