Journal ArticleDOI
Relativistic simulations of rotational core collapse - II. Collapse dynamics and gravitational radiation
TL;DR: In this article, the relativistic rotational supernova core collapse in axisymmetry has been studied and the gravity radiation emitted by such an event has been computed using hydrodynamic simulations.
Journal ArticleDOI
Exploring the relativistic regime with Newtonian hydrodynamics: an improved effective gravitational potential for supernova simulations
TL;DR: In this paper, a modified effective relativistic potential for self-gravitating fluids is proposed for hydrodynamical simulations of stellar core collapse and post-bounce evolution.
Journal ArticleDOI
Relativistic simulations of rotational core collapse. II. Collapse dynamics and gravitational radiation
TL;DR: In this article, a hydrodynamic simulation of relativistic rotational supernova core collapse in axisymmetry was performed and the gravitational radiation emitted by such an event was computed.
Journal ArticleDOI
Exploring the relativistic regime with Newtonian hydrodynamics: An improved effective gravitational potential for supernova simulations
TL;DR: In this paper, the authors investigated the possibility to approximate relativistic effects in hydrodynamical simulations of stellar core collapse and post-bounce evolution by using a modified gravitational potential in an otherwise standard Newtonian hydrodynamic code.
Journal ArticleDOI
Gravitational wave burst signal from core collapse of rotating stars
TL;DR: In this article, a general relativistic simulation of stellar core collapse to a proto-neutron star is presented, using two different micro-physical nonzero-temperature nuclear equations of state as well as an approximate description of deleptonization during the collapse phase.
