Rotating neutron stars in the first order post-Newtonian approximation
Athanasios Fotopoulos, Vasileios G. Karageorgopoulos, Vassilis S. Geroyannis
We study models of uniformly and differentially rotating neutron stars in the framework of post-Newtonian approximation in general relativity as established by Chandrasechar. In pa…
Jet bending and velocity profiles
I. Liodakis, V. S. Geroyannis, V. G. Karageorgopoulos
In this study, we consider the problem of geometry of curved jets. We work with a simplified two-dimensional kinematical model assuming that the jet velocity is varying. We prescri…
Critical rotation of general-relativistic polytropic models simulating neutron stars: a post-Newtonian hybrid approximative scheme
Vassilis S. Geroyannis, Vasileios G. Karageorgopoulos
We develop a "hybrid approximative scheme" in the framework of the post-Newtonian approximation for computing general-relativistic polytropic models simulating neutron stars in cri…
