Semi-global simulations of the magneto-rotational instability in core collapse supernovae
M. Obergaulinger, P. Cerdà-Duràn, E. Müller +1
Possible effects of magnetic fields in core collapse supernovae rely on an efficient amplification of the weak pre-collapse fields. It has been suggested that the magneto-rotationa…
The core helium flash revisited: I. One and two-dimensional hydrodynamic simulations
M. Mocak, E. Mueller, A. Weiss +1
We investigate the hydrodynamics of the core helium flash near its peak. Past research concerned with the dynamics of this event is inconclusive. However, the most recent multidime…
Exploring the relativistic regime with Newtonian hydrodynamics: II. An effective gravitational potential for rapid rotation
Bernhard Mueller, Harald Dimmelmeier, Ewald Mueller
We present the generalization of a recently introduced modified gravitational potential for self-gravitating fluids. The use of this potential allows for an accurate approximation…
Non-axisymmetric instability and fragmentation of general relativistic quasi-toroidal stars
Burkhard Zink, Nikolaos Stergioulas, Ian Hawke +3
In a recent publication, we have demonstrated that differentially rotating stars admit new channels of black hole formation via fragmentation instabilities. Since a higher order in…
