Simultaneous determination of mass parameter and radial marker in Schwarzschild geometry
Victor Varela, Lorenzo Leal
We show that mass parameter and radial coordinate values can be indirectly measured in thought experiments performed in Schwarzschild spacetime, without using the Newtonian limit o…
A note on linearized stability of Schwarzschild thin-shell wormholes with variable equations of state
Victor Varela
We discuss how the assumption of variable equation of state (EoS) allows the elimination of the instability at equilibrium throat radius featured by previous Schwarzschild…
Charged anisotropic matter with linear or nonlinear equation of state
Victor Varela, Farook Rahaman, Saibal Ray +2
Ivanov pointed out substantial analytical difficulties associated with self-gravitating, static, isotropic fluid spheres when pressure explicitly depends on matter density. Simplif…
Neutral perfect fluids and charged thin shells with electromagnetic mass in general relativity
Victor Varela
We build extended sources for the Reissner-Nordström metric. Our models describe a neutral perfect fluid core bounded by a charged thin shell, and feature everywhere positive rest…
Neutral perfect fluids of Majumdar-type in general relativity
V. Varela
We consider the extension of the Majumdar-type class of static solutions for the Einstein-Maxwell equations, proposed by Ida to include charged perfect fluid sources. We impose the…
Construction of Sources for Majumdar-Papapetrou Spacetimes
Victor Varela
We study Majumdar-Papapetrou solutions for the 3+1 Einstein-Maxwell equations, with charged dust acting as the external source for the fields. The spherically symmetric solution of…
