We study spherically symmetric timelike thin-shells in 3 + 1−dimensional bulk spacetime with a variable equation of state for the fluid presented on the shell. In such a fluid the angular pressure p is a function of both surface energy density σ and the radius R of the thin-shell. Explicit cases of the thin shells connecting two non-identical cloud of strings spacetimes and a flat Minkowski spacetime to the Schwarzschild metric are investigated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
