Orbit classification in a disk galaxy model with a pseudo-Newtonian central black hole
Euaggelos E. Zotos, F. L. Dubeibe, André F. Steklain +1
We numerically investigate the motion of stars on the meridional plane of an axially symmetric disk galaxy model, containing a central supermassive black hole, represented by the P…
Orbital and escape dynamics in barred galaxies -- IV. Heteroclinic connections
Euaggelos E. Zotos, Christof Jung
Continuing the series of papers on a new model for a barred galaxy, we investigate the heteroclinic connections between the two normally hyperbolic invariant manifolds sitting over…
Orbit classification in an equal-mass non-spinning binary black hole pseudo-Newtonian system
Euaggelos E. Zotos, Fredy L. Dubeibe, Guillermo A. González
The dynamics of a test particle in a non-spinning binary black hole system of equal masses is numerically investigated. The binary system is modeled in the context of the pseudo-Ne…
Correlating the escape dynamics and the role of the normally hyperbolic invariant manifolds in a binary system of dwarf spheroidal galaxies
Euaggelos E. Zotos, Christof Jung
We elucidate the escape properties of stars moving in the combined gravitational field of a binary system of two interacting dwarf spheroidal galaxies. A galaxy model of three degr…
Orbital and escape dynamics in barred galaxies - III. The 3D system: Correlations between the basins of escape and the NHIMs
Euaggelos E. Zotos, Christof Jung
The escape dynamics of the stars in a barred galaxy composed of a spherically symmetric central nucleus, a bar, a flat thin disk and a dark matter halo component is investigated by…
Distinguishing between order and chaos in a simple barred galaxy model
Euaggelos E. Zotos
We use a simple dynamical model in order to investigate the regular or chaotic character of orbits in a barred galaxy with a central, spherically symmetric, dense nucleus and a fla…
