Jakob Lysgaard Rørsted

During his PhD studies, Jakob Lysgaard Rørsted researched computer models of stars like our Sun. Such computer models can help researchers understand the properties of the stars we observe and are invaluable for many different branches of astrophysics. One phenomenon which is particularly challenging to describe is convection: the turbulent motion of gas near the surface of solar-like stars.

Jakob has studied how to improve the present stellar models using advanced supercomputer-simulations of convection. The new research findings contribute to the future generation of computer models of stars, which will help in the search for a deeper understanding of stars, planets, galaxies, and the universe.

The PhD degree was completed at the Stellar Astrophysics Centre (SAC), Department of Physics and Astronomy, Faculty of Natural Sciences, Aarhus University.
