Astronomy & Astrophysics Seminar: Exploding massive stars with jets

Abstract:

I will present the idea that all core collapse supernovae are exploded by jets launched from the newly born neutron star or black hole. This model is motivated in part by the failure of the 30-years old delayed-neutrino mechanism to explode stars with the desired energy of 1e51 erg. The jets operate in a negative feedback mechanism. This jet feedback mechanism (JFM) explains why most supernovae explode with a typical kinetic energy of several times the binding energy of the stellar core. The JFM can also explain super-energetic supernovae. I call for a paradigm shift from neutrino-based explosions to jet-driven explosions for core collapse supernovae.
