Nonlinear vacuum electrodynamics influence on the spacetime structure and massive particles orbits properties in Einstein–Born–Infeld theory

In this paper, we studied how nonlinear vacuum electrodynamics can affect charged collapsar spacetime structure and properties of particles movement in this spacetime. Analysis of uncharged particle orbits stability shows that the main features of this orbit in Reissner–Nordström spacetime remains actual for Einstein–Born–Infeld theory. At the same time, there is a significant quantitative difference between stable orbits parameters in these theories and this fact may influence on accretion rate predictions for charged collapsar.
