Numerical simulations of neutron stars — •Marcus Thierfelder, Sebastiano Bernuzzi, David Hilditch, and Bernd Brügmann — Theoretisch-Physikalisches Institut, FSU Jena

Numerical relativity simulations are of fundamental importance for the theoretical modelization of the gravitational signal emitted. In this talk we present a new code designed to study binary neutron star mergers in full general relativity. We discuss several tests that validate the code and describe our recent results on the gravitational collapse to black-hole obtained with the puncture gauge. We present preliminary results on the accuracy of the gravitational waves emitted by binary neutron star mergers in our computations.
