Nonlinear Perturbations of Relativistic Stars
K. J. Kwon, Abhishek Hegade K. R., Tejaswi Venumadhav +2
We extend the general relativistic Lagrangian perturbation formalism of Friedman and Schutz [Astrophys. J. 200, 204 (1975)] beyond linear order, retaining full time dependence of t…

Impact on Inferred Neutron Star Equation of State due to Nonlinear Hydrodynamics, Background Spin, and Relativity
Joseph Bretz, Hang Yu
Tidal interaction is a unique, detectable signature in gravitational wave signals from inspiraling binary neutron stars (BNSs), which can be used to constrain the neutron star (NS)…
