The marginally trapped surfaces in spheroidal spacetimes
Published 27 Apr 2018 in gr-qc and hep-th | (1804.11218v3)
Abstract: We study the location of marginally trapped surfaces in space-times resulting from an axial deformation of static isotropic systems, and show that the Misner-Sharp mass evaluated on the corresponding undeformed spherically symmetric space provides the correct gravitational radius to locate the spheroidal horizon.
