Parametrized equation of state for neutron star matter with continuous sound speed

MF O'Boyle, C Markakis, N Stergioulas, JS Read - Physical Review D, 2020 - APS
We present a generalized piecewise polytropic parametrization for the neutron-star equation
of state using an ansatz that imposes continuity in not only pressure and energy density, but …

Increasing the accuracy of binary neutron star simulations with an improved vacuum treatment

A Poudel, W Tichy, B Brügmann, T Dietrich - Physical Review D, 2020 - APS
Numerical-relativity simulations are essential for studying the last stages of the binary
neutron star coalescence. Unfortunately, for stable simulations there is the need to add an …
