Binary Neutron Star Mergers and Short Gamma-Ray Bursts: Effects of Magnetic Field Orientation, Equation of State, and Mass Ratio

28 Oct 2016 Kawamura Takumu Giacomazzo Bruno Kastaun Wolfgang Ciolfi Riccardo Endrizzi Andrea Baiotti Luca Perna Rosalba

We present fully GRMHD simulations of the merger of binary neutron star (BNS) systems. We consider BNSs producing a hypermassive neutron star (HMNS) that collapses to a spinning black hole (BH) surrounded by a magnetized accretion disk in a few tens of ms. We investigate whether such systems may launch relativistic jets and power short gamma-ray bursts... (read more)
