Abstract

Recently, it became possible to investigate systematically the binary neutron star (BNS) system parameter space varying total mass, mass-ratio, eccentricity, spin, and the equation of state (EOS) simultaneously. The scope of this project is to perform new numerical simulation of generic BNS systems focusing on precessing configurations. This will give new insights to the physics of BNS system mergers by including previously inaccessible regions of the BNS parameter space helping to improve gravitational wave modeling. We also plan to release in the near future a final public catalog of BNS merger data, which is the first catalog for BNS systems, with a systematic study of the BNS parameter space including also precessing systems.
