Frolov Black Hole Surrounded by a Cloud of Strings
F. F. Nascimento, J. C. Rocha, V. B. Bezerra +1
We obtain the metric which describes the spacetime corresponding to the Frolov black hole in the presence of a cloud of strings and discuss how this cloud affects the regularity of…
Charged Bardeen black hole with a cosmological constant and surrounded by quintessence and a cloud of strings
F. F. Nascimento, V. B. Bezerra, J. M. Toledo +2
Exact solutions which generalize the Bardeen black hole solution, in the sense that several sources are taken into account, are derived. The most general case corresponds to a char…
Charged Hayward black hole with a cosmological constant and surrounded by quintessence and a cloud of strings
F. F. Nascimento, V. B. Bezerra, J. M. Toledo +1
A family of exact solutions extending the Hayward black hole by incorporating multiple sources is obtained. The most comprehensive scenario describes a charged Hayward black hole w…
Some remarks on Frolov-AdS black hole surrounded by a fluid of string
F. F. Nascimento, V. B. Bezerra, J. M. Toledo +2
A class of new solutions that generalizes the Frolov regular black hole solution is obtained. The generalization is performed by adding the cosmological constant and surrounding th…
Some remarks on Hayward-AdS black hole surrounded by a fluid of strings
F. F. Nascimento, V. B. Bezerra, J. M. Toledo +1
We obtain a class of solutions corresponding to a generalization of the Hayward black hole by solving the Einstein equations coupled to a particular nonlinear electromagnetic field…
