Effects of Chiral Effective Field Theory Equation of State on Binary Neutron Star Mergers

Understand

We present fully general relativistic simulations of binary neutron star mergers, employing a new zero- temperature chiral effective field theory equation of state, the BL EOS.

• We offer a comparison with respect to the older GM3 EOS, which is based on standard relativistic mean field theory, and separately determine the impact of the mass.
• We provide a detailed analysis of the dynamics, with focus on the post-merger phase.
• For all models, we extract the gravitational wave strain and the post-merger frequency spectrum.
