Abstract

The results of gravitational wave GW 170817, which was observed after the binary neutron star merger, can be put to use for tightly constraining the mass and radius of neutron stars. We calculate the mass and radius of neutron stars using a parameterized post-TOV model. The model has several free parameters that provide more flexibility than that of standard general relativity (GR) compared to the observational data. We have found that for a particular combination of the corresponding free parameters, the post-TOV model's mass-radius predictions are compatible with those of GW170817 data.
