Semi-analytical estimates for the chaotic diffusion in the Second Fundamental Model of Resonance. Application to Earth's navigation satellites
Edoardo Legnaro, Christos Efthymiopoulos, Maria Harsoula
We discuss the applicability of the Melnikov and Landau-Teller theories in obtaining semi-analytical estimates of the speed of chaotic diffusion in systems driven by the separatrix…
Asymptotic Orbits in Barred Spiral Galaxies
Maria Harsoula, Constantinos Kalapotharakos, George Contopoulos
We study the formation of the spiral structure of barred spiral galaxies, using an -body model. The evolution of this -body model in the adiabatic approximation maintains a s…
Orbital structure in barred spiral galaxies
Maria Harsoula, Constantinos Kalapotharakos
We study the orbital structure in a series of self-consistent -body configurations simulating rotating barred galaxies with spiral and ring structures. We perform frequency anal…
