Revealing the escape mechanism of three-dimensional orbits in a tidally limited star cluster
Euaggelos E. Zotos
The aim of this work is to explore the escape process of three-dimensional orbits in a star cluster rotating around its parent galaxy in a circular orbit. The gravitational field o…
Determining the nature of orbits in a three-dimensional galaxy model hosting a BL Lacertae object
Euaggelos E. Zotos
A three-dimensional dynamical model for a galaxy hosting a BL Lacertae object is constructed. The model consists of a logarithmic potential representing an elliptical host galaxy w…
Orbit classification of low and high angular momentum stars
Euaggelos E. Zotos
We determine the character of orbits of stars moving in the meridional plane of an axially symmetric time-independent disk galaxy model with a spherical central nucleus. In…
How does the Structure of Spherical Dark Matter Halos Affect the Types of Orbits in Disk Galaxies?
Euaggelos E. Zotos
The main objective of this work is to determine the character of orbits of stars moving in the meridional plane of an axially symmetric time-independent disk galaxy model w…
Classifying orbits in galaxy models with a prolate or an oblate dark matter halo component
Euaggelos E. Zotos
We explore the nature of orbits of stars moving in the meridional plane of an axially symmetric galactic model with a disk, a spherical nucleus, and a flat biaxial dark mat…
A Hamiltonian system of three degrees of freedom with eight channels of escape: The Great Escape
Euaggelos E. Zotos
In this work, we try to shed some light to the nature of orbits in a three-dimensional potential of a perturbed harmonic oscillator with eight possible channels of escape, which wa…
