We show a simulation of two neutron stars in a grazing collision based on the full Einstein equations coupled to general relativistic hydrodynamic equations. The coalescences of neutron star binaries have attracted much attention as sources of gravitational radiation and candidates of gamma-ray burst.
The simulation is carried out with a 3D code called "Cactus" that is currently being developed by our NCSA/Potsdam/Wash U Numerical Relativity Collaboration, together with other research groups in the community. The study of neutron star coalescences is performed as part of the NASA Neutron Star Grand Challenge Project (NASA HPCC NCCS5-153). The computation is carried out at the NSF SuperComputing Centers under National Resource Allocation MCA 93S025.
