TAPIR Seminar

Microphysics, including thermochemistry and radiative transfer, are important in various astrophysical systems but difficult to compute. Equipped with the computation power of GPUs, dispersal of protoplanetary disks and planet atmospheres are studied by coupling consistent microphysics with (magneto-)hydrodynamics in photoevaporation driven by ultraviolet and X-ray radiation from the host star. I will present the updated understandings towards underlying processes, that determine the local thermo-/hydrodynamic evolution and the global structures, of photoevaporating systems. I will also discuss predictions to observables based on those numerical models.
