Neutrino-driven supernovae: An accretion instability in a nuclear physics controlled environment

https://doi.org/10.1016/j.nuclphysa.2005.05.008Get rights and content

New simulations demonstrate that low-mode, nonradial hydrodynamic instabilities of the accretion shock help starting hot-bubble convection in supernovae and thus support explosions by the neutrino-heating mechanism. The prevailing conditions depend on the high-density equation of state which governs stellar core collapse, core bounce, and neutron star formation. Tests of this sensitivity to nuclear physics variations are shown for spherically symmetric models. Implications of current explosion models for r-process nucleosynthesis are addressed.

      The shock is weakened so much that it finally stalls and turns into an accretion shock at a radius between 100 and 200 km, i.e., the matter downstream of the shock has negative velocities and continues falling inward (Fig. 1, middle right panel). All state-of-the-art simulations of stellar core collapse performed in Newtonian gravity [8,9], with an approximative treatment of general relativity [10–12], in full general relativity [13–17], and with stiff or soft nuclear equations of state currently available for core-collapse simulations [18–21] (see also Section 2.1) agree with the models of the 1980's and 1990's (e.g., [22–25]) that the prompt shock is unable to trigger supernova explosions.1 After the core bounce, a compact remnant begins to form at the center of the collapsing star, rapidly growing by the accretion of infalling stellar material until the explosion sets in.
