Special Features of Galactic Dynamics
Christos Efthymiopoulos, Nikos Voglis, Constantinos Kalapotharakos
The present lecture notes are an introduction to selected topics of {\it Galactic Dynamics}. The focus is on topics that we consider more relevant to the main theme of this worksho…
Invariant manifolds, phase correlations of chaotic orbits and the spiral structure of galaxies
Nikos Voglis, Panagiotis Tsoutsis, Christos Efthymiopoulos
In the presence of a strong component in a rotating galaxy, the phase space structure near corotation is shaped to a large extent by the {\it invariant manifolds} of the shor…
Chaotic motion and spiral structure in self-consistent models of rotating galaxies
N. Voglis, I. Stavropoulos, C. Kalapotharakos
Dissipationless N-body models of rotating galaxies, iso-energetic to a non-rotating model, are examined as regards the mass in regular and in chaotic motion. The values of their sp…
