Jacobi stability of circular orbits around conformally invariant Weyl gravity black holes
Cristina Blaga, Paul A. Blaga
Weyl conformal gravity was originally proposed in the early twentieth century as an attempt to unify gravitation and electromagnetism. Since 1989, renewed interest in this fourth-o…
Jacobi and Lyapunov stability analysis of circular geodesics around a spherically symmetric dilaton black hole
Cristina Blaga, Paul Blaga, Tiberiu Harko
We analyze the stability of the geodesic curves in the geometry of the Gibbons-Maeda-Garfinkle-Horowitz-Strominger black hole, describing the space time of a charged black hole in…
Periastron precession for an extremal spherically symmetric dilaton black hole
Paul Blaga, Cristina Blaga
The purpose of this article is to obtain the periastron precession of a free particle moving around an extremal spherically symmetric dilaton black hole. To get the formulae for th…
Phase-plane analysis of the timelike geodesics around a spherically symmetric static dilaton black hole
Paul Blaga, Cristina Blaga
In this note we take a dynamical systems approach to the equations of motion of a free test particle moving around a spherically symmetric static dilaton black hole, written in the…
Circular orbits, Lyapunov stability and Manev-type forces
Cristina Blaga
In this article we study the stability in the sense of Lyapunov of the circular orbits in the generalized Manev two bodies problem. First, we explore the existence of the circular…
