Talk Title

The propagation of relativistic jets in massive progenitor stars and beyond

Abstract

I will review the propagation of relativistic jets inside their progenitor star and after they break out of their surface. The discussion will be both analytical and based on numerical simulations of hydrodynamic jets. I will show how some common approximation of the jet acceleration are misleading and connect the jet properties to their radiation signature.
