""How Stars move in Galactic Disks""
I will discuss the radial motion of stars in galactic disks, triggered by resonant-scattering with spiral structures. In particular, I will assess the importance of this process on the overall structure of the galaxy and revisit some controversial conclusions on the subject, such as the emergence of a thick disk and how this correlates with the conservation of some integrals of motion.
