Initial Data for Eccentric Neutron Star Binaries — •Niclas Moldenhauer and Charalampos Markakis — Friedrich-Schiller Universität, Jena, Germany

We present a way to construct initial data for neutron star binaries on quasi-circular or eccentric orbits. Therefore, a self-consistent field method is used, in which we solve the Einstein constraints in the conformal thin-sandwich approach. A single TOV star can be constructed in this way and afterwards, two such TOV stars are superimposed. Then the method is applied again to minimize the constraint violations and induce tidal deformations.
