Collapse of spherical charged anisotropic fluid spacetimes

A class of spherical collapsing exact solutions with electromagnetic charge is derived. This class of solutions—in general anisotropic—contains however as a particular case the charged dust model already known in the literature. Under some regularity assumptions that in the uncharged case give rise to naked singularities, it is shown that the process of avoidance of shell focusing singularities—already known for the dust collapse (Krasinski et al 2006 Phys. Rev. D 73 124033)—also takes place here, determining shell crossing effects or a completely regular solution.

Abstract:	A class of spherical collapsing exact solutions with electromagnetic charge is derived. This class of solutions—in general anisotropic—contains however as a particular case the charged dust model already known in the literature. Under some regularity assumptions that in the uncharged case give rise to naked singularities, it is shown that the process of avoidance of shell focusing singularities—already known for the dust collapse (Krasinski et al 2006 Phys.
