For simulations of physical processes in stars in the framework of project HWB07 “Multidimensional Hydrodynamic Simulations of Stars”, the PSO group was awarded 27 million core hours on the JUQUEEN supercomputer at Jülich Supercomputing Centre (Forschungszentrum Jülich). These resources, allocated for May 2017 to April 2018, will be used to perform simulations of convective burning processes and dynamical shear instabilities in stars with the Seven-League Hydro code developed by the PSO group.
Conventional stellar evolution calculations cover the entire lives of stars and are too challenging to be performed in a detailed multidimensional hydrodynamic treatment with current computational resources and methods. The goal of project HWB07 is therefore to perform such detailed simulations for shorter phases and isolated processes that are critical for the further evolution. Such simulations are still extremely demanding and require substantial amounts of computer time as well as innovative modeling approaches. Their results will help to improve the reliability and predictivity of stellar modelling.
The Heidelberg Institute for Theoretical Studies (HITS) was established in 2010 by the physicist and SAP co-founder Klaus Tschira (1940-2015) and the Klaus Tschira Foundation as a private, non-profit research institute. HITS conducts basic research in the natural sciences, mathematics and computer science, with a focus on the processing, structuring, and analyzing of large amounts of complex data and the development of computational methods and software. The research fields range from molecular biology to astrophysics. The shareholders of HITS are the HITS-Stiftung, which is a subsidiary of the Klaus Tschira Foundation, Heidelberg University and the Karlsruhe Institute of Technology (KIT). HITS also cooperates with other universities and research institutes and with industrial partners. The base funding of HITS is provided by the HITS Stiftung with funds received from the Klaus Tschira Foundation. The primary external funding agencies are the Federal Ministry of Education and Research (BMBF), the German Research Foundation (DFG), and the European Union.
