Abstract

We study the turbulent convection during the core helium flash at its peak with our code HERAKLES. Our 3D hydrodynamic simulations of the core helium flash performed on the LRZ’s ALTIX 4700 allowed us to investigate differences between the 3D models and our earlier models in 2D and 3D using the same initial conditions and angular resolution. We mainly studied the onset of the convection where part of the released thermonuclear energy via helium triple α burning is transported away by material flow from the burning regions inhibiting thereby a thermonuclear explosion.
