Beyond second-order convergence in simulations of binary neutron stars in full general relativity
Beyond second-order convergence in simulations of binary neutron stars in full general relativity
Despite the recent rapid progress in numerical relativity, a convergence order less than the second has so far plagued codes solving the Einstein-Euler system of equations. We report simulations of the inspiral of binary neutron stars in quasi-circular orbits computed with a new code employing high-order, high-resolution shock-capturing, finite-differencing schemes …
