In this semester the seminar “Modelling of materials – theory, model reduction and efficient numerical methods” will take place every Wednesday from 9:00 till 10:00 in the room K3. This week the talk will be given by Ondřej Pejcha. Please see the details below.

Title: Death of single and binary stars
Abstract: I will provide an overview of my results in the theory of core-collapse supernova explosions and catastrophic interactions of binary stars. Many of these results were obtained by solving various modifications of Euler equations of compressible hydrodynamics. I will specifically mention steady-state solutions obtained by relaxation, smoothed particle hydrodynamics combined with flux-limited radiative diffusion, and 2D and 3D finite volume hydrodynamics with adaptive mesh refinement, on moving meshes, or combined with radiation transport. I will conclude by discussing ideas about future work with discontinuous Galerkin on curvilinear meshes.
