Improvements on Initial Data for Spinning Neutron Star Binaries — •Hannes Rüter — Max-Planck-Institut für Gravitationsphysik, Potsdam/Golm

The current formalism to construct numerical relativity initial data for neutron star binaries with spin makes some assumptions that are not compatible with the constraints given by energy-momentum conservation. This talk will discuss issues of the current formalism and propose possible solutions and improvements, which will be important for future high accuracy binary neutron star simulations.
