On black holes with scalar hairs
Changjun Gao, Jianhui Qiu
By using the Taylor series method and the solution-generating method, we construct exact black hole solutions with minimally coupled scalar field. We find that the black hole solut…
New understanding of Majumdar-Papapetrou and Perjés-Israel-Wilson solutions
Changjun Gao
Hartle and Hawking have shown that, except for the case of only point monopoles as sources, both the Majumdar-Papapetrou and the Perjés-Israel-Wilson solutions have naked singulari…
Extending Bekenstein's theorem in order to search exact solutions of Einstein-Maxwell-conformal-scalar equations
Jianhui Qiu, Changjun Gao
The Bekenstein's theorem allows us to generate a Einstein-conformal scalar solution from a single Einstein-ordinary scalar solution. In this article, we extend this theorem to Eins…
Black Holes With Many Horizons in the Theories of Nonlinear Electrodynamics
Changjun Gao
In this article, we construct exact black hole solutions with many horizons (more than number two) in the Einstein-nonlinear electrodynamic theories. In particular, we acquire the…
