Charged gravastars admitting conformal motion
A A Usmani, Farook Rahaman, Saibal Ray +4
We propose a new model of a {\it gravastar} admitting conformal motion. While retaining the framework of the Mazur-Mottola model, the gravastar is assumed to be internally charged,…
Thin-shell wormholes from charged black holes in generalized dilaton-axion gravity
A. A. Usmani, F. Rahaman, Saibal Ray +3
This paper discusses a new type of thin-shell wormhole constructed by applying the cut-and-paste technique to two copies of a charged black hole in generalized dilaton-axion gravit…
Thin-shell wormholes from regular charged black holes
F. Rahaman, K A Rahman, Sk. A Rakib +1
We investigate a new thin-shell wormhole constructed by surgically grafting two regular charged black holes arising from the action using nonlinear electrodynamics coupled to gener…
Wormholes supported by polytropic phantom energy
Mubasher Jamil, Peter K. F. Kuhfittig, Farook Rahaman +1
It is generally agreed that the acceleration of the Universe can best be explained by the presence of dark or phantom energy. The equation of state of the latter shows that the nul…
