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…
Bondi accretion disk luminosity around neutral and charged Simpson-Visser spacetimes
Serena Gambino, Roberto Giambò, Orlando Luongo
We investigate relativistic Bondi accretion in the Simpson-Visser spacetime, which, via a single parameter , interpolates between the Schwarzschild, regular black hole, extre…
Generalizing the relativistic precession model of quasi-periodic oscillations through anharmonic corrections
Roberto Giambò, Orlando Luongo, Marco Muccino +1
We critically reanalyze the relativistic precession model of quasi-periodic oscillations, exploring its natural extension beyond the standard harmonic approximation. To do so, we s…
