How does the Mass Transport in Disk Galaxy Models Influence the Character of Orbits?
We explore the regular or chaotic nature of orbits of stars moving in the meridional (R, z) plane of an axially symmetric time-dependent disk galaxy model with a central, spherically symmetric nucleus.In particular, mass is linearly transported from the disk to the galactic nucleus, in order to mimic, in a way, the case of self-consistent interacti
