Binary neutron stars: inspiral and merger

When binary neutron stars inspiral and finally merge they emit gravitational waves.

High mass ratio binary neutron star merger 

This animation shows the density, ejected material, and gravitational waves for a binary neutron star merger consisting of one 1.5 and one 1.0 solar mass neutron star.

Numerical relativity simulation of two merging neutron stars with 1.5 and 1.0 solar masses (density, gravitational wave and ejected material)

The different panels refer to: upper left: 2D density profile in the equatorial plane with increasing density from dark blue to dark red; upper right: density profile as shown left together with unbound/ejected material (brown to green); lower left panel: 3D density rendering (yellow) together with the unbound material (blue); lower right: gravitational wave signal (black) and the corresponding frequency (red).
