Adjusting chaotic indicators to curved spacetimes
Georgios Lukes-Gerakopoulos
In this work, chaotic indicators, which have been established in the framework of classical mechanics, are reformulated in the framework of general relativity in such a way that th…
Comment on "Nonexistence of the final first integral in the Zipoy-Voorhees space-time"
Georgios Lukes-Gerakopoulos, Andrzej J. Maciejewski, Maria Przybylska +1
The accuracy of the numerical findings of Lukes-Gerakopoulos PRD 86, 044013 (2012), regarding the existence of additional first integrals in the Zipoy-Voorhees space-time, was rece…
Mind the Resonances: Final stages of accretion into bumpy black holes
Georgios Lukes-Gerakopoulos, George Contopoulos
In this article we discuss a possible way of testing the Kerr black hole hypothesis by taking advantage of phenomena correlated with chaotic motion in the final stages of an accret…
Testing the existence of regions of stable orbits at small radii around black hole candidates
Cosimo Bambi, Georgios Lukes-Gerakopoulos
Black hole candidates in X-ray binary systems and at the centers of galaxies are expected to be the Kerr black holes of General Relativity, but the actual nature of these objects h…
