Photon surface extensions in general spherical dust collapse
Roberto Giambò, Camilla Lucamarini
We extend the analysis of photon surfaces in spherical dust collapse to the general, non-marginally bound case, i.e.\ allowing the \textit{energy function} of the Lema\^ıtre…

Photon surfaces extensions for dynamical gravitational collapse
Roberto Giambò, Camilla Lucamarini
The equations for the photon surface in spherical symmetry are worked out, starting from arXiv:gr-qc/0005050, in the most general dynamical setting. We show that the condition for…
