Non-radial pulsations of gravitationally coupled two-fluid neutron stars in general relativity
Ankit Kumar, Daniel A. Caballero, Hajime Sotani +1
Non-radial oscillations of neutron stars provide a powerful probe of stellar structure and relativistic gravity, but a fully general relativistic treatment for gravitationally coup…
Neutron Star Radial Perturbations for Causal, Viscous, Relativistic Fluids
Daniel A. Caballero, Nicolás Yunes
Which of the multiple models of causal and stable relativistic viscous fluids that have been developed is best suited to describe neutron stars? The modeling of out-of-equilibrium…
Radial Mode Stability of Two-Fluid Neutron Stars
Daniel A. Caballero, Justin L. Ripley, Nicolás Yunes
Radial mode stability is a necessary condition for the astrophysical viability of compact objects. In recent years, astrophysical models with two fluids have gain popularity, espec…
Damped and Driven Breathers and Metastability
Daniel A. Caballero, C. Eugene Wayne
In this article we prove the existence of a new family of periodic solutions for discrete, nonlinear Schrodinger equations subject to spatially localized driving and damping. They…
