The coalescence of invariant manifolds and the spiral structure of barred galaxies
P. Tsoutsis, C. Efthymiopoulos, N. Voglis
In a previous paper (Voglis et al. 2006a, paper I) we demonstrated that, in a rotating galaxy with a strong bar, the unstable asymptotic manifolds of the short period family of uns…
