@article{Montero2011RelativisticCA, title={Relativistic collapse and explosion of rotating supermassive stars with thermonuclear effects}, author={Pedro J. Montero and Hans-Thomas Janka and E. R. Mueller}, journal={arXiv: Cosmology and Nongalactic Astrophysics}, year={2011} }
We present results of general relativistic simulations of collapsing supermassive stars with and without rotation using the two-dimensional general relativistic numerical code Nada, which solves the Einstein equations written in the BSSN formalism and the general relativistic hydrodynamics equations with high resolution shock capturing schemes. These numerical simulations use an equation of state which includes effects of gas pressure, and in a tabulated form those associated with radiation and…
