- Abstract:
- The explosion mechanism of core-collapse supernovae is not yet fully understood. Two candidate mecha-
nisms exist: magnetically-driven explosions and neutrino-driven explosions. Initial simulations with spher-
ical (1-dimensional) and axial (2-dimensional) symmetry did not yield robust explosions, despite including
neutrino-heating in their models. Instead these simulations saw the post-bounce shock stall, never making it
to the surface of the star to cause explosions that would be visible from Earth. Current 3-dimensional general
relativistic simulations, such as the one featured in Ott et al. (2013), study the explosion mechanism in greater
detail to draw conclusions about the supernova from the observed signal. To do so, the shock must be simulated
with high-resolution, but increasing the resolution of the entire simulation is too computationally costly. We
develop a routine in the Einstein Toolkit that finds the location of the shock at any time and applies adaptive
mesh refinement to resolve the shock surface without resolving unimportant regions.
