Description
I will present results from numerical simulations of binary neutron star mergers with emphasis on the structure of the merger remnants during the phase shortly after merger, when the GW signal might still be detectable before the amplitude becomes too small. The fluid flow and radial mass distribution determined numerically has implications regarding the question which physical effects are relevant for the remnant lifetime. This should be addressed in order to better constrain the equation of state from future observations of remnant lifetimes. Further, I will discuss the occurrence of phase jumps in the GW signal during and sometimes also after merger and how those further complicate the interpretation of secondary peaks in the GW power spectrum. Finally, I will discuss the impact of the initial NS spin on the late inspiral and post-merger phases.
