Analysis of the Conformally Flat Approximation for Binary Neutron Star Initial Conditions

Figure 7

Plot of the orbital angular velocity, , versus cycle. When stops changing with time the simulation has reached a circular binary orbit solution. The run ( for  cm²) goes over ~10 obits and then becomes unstable to inspiral and merger after ~10⁴ cycles. The stable two runs ( for  cm⁻² and for  cm⁻²) were run for 100,000 cycles and ≈100 orbits.
