High-performance computation (HPC) is central to modern astronomy. Moreover, the diversity of astronomy as a science results in models with very different computational requirements.

In this presentation, I will show-case three representative astrophysical problems which strongly rely on HPC in different ways. These include the models of how mergers of white dwarf stars may lead to type 1a supernovae, which are among the brightest explosions in the universe; simulations of binary stars with a detailed stellar evolution code, which demonstrate how these stars trace the history of our Galaxy; and finally, the evolution of triple stars, for which using correct models of stellar interactions make a substantial effect on their present-day orbits.

This online session is open to all. It will use the Blackboard Collaborate platform.
