Cylindrically symmetric inhomogeneous dust collapse with a zero expansion component
arXiv:1709.10458 · doi:10.1088/1361-6382/aa8aa8
Abstract
We investigate a class of cylindrically symmetric inhomogeneous -dust spacetimes which have a regular axis and some zero expansion component. For , we obtain new exact solutions to the Einstein equations and show that they are unique, within that class. For , we recover the Senovilla-Vera metric and show that it can be locally matched to an Einstein-Rosen type of exterior. Finally, we explore some consequences of the matching, such as trapped surface formation and gravitational radiation in the exterior.
