Towards a Realistic Neutron Star Binary Inspiral: Initial Data and Long Timescale Evolution

Abstract:

I present results produced by my fully consistent general relativistic hydrodynamics numerical relativity code. First, I analyze the conformally flat, quasiequilibrium (CFQE) sequence approximation by directly comparing it to solutions of the Einstein equations obtained numerically using CFQE configurations as initial data. In this way, I demonstrate how one can go about constructing astrophysically relevant initial data sets. I then perform the first detailed analysis of the characteristics of the orbital motion of finite sized compact objects in numerical relativity in full 3+1 numerical relativity.
