Structures induced by companions in galactic discs
P. Kyziropoulos, C. Efthymiopoulos, G. Gravvanis +1
Using N-body simulations we study the structures induced on a galactic disc by repeated flybys of a companion in decaying eccentric orbit around the disc. Our system is composed by…

Effective power-law dependence of Lyapunov exponents on the central mass in galaxies
N. Delis, C. Efthymiopoulos, C. Kalapotharakos
Using both numerical and analytical approaches, we demonstrate the existence of an effective power-law relation between the mean Lyapunov exponent of stellar orb…
