Hairy mass bound in the Einstein-Born-Infeld black hole
arXiv:1201.1173 · doi:10.1103/PhysRevD.86.084047
Abstract
We study the Einstein-Born-Infeld (EBI) theory where the hairy black hole was found as the EBI black hole by using Hod's idea. The hair extends beyond the photon-sphere of the EBI black hole spacetimes. We show that the region beyond the photon-sphere involves more than half of the total hair's mass, which respects Hod's conjectured bound.
