Dynamical Evolution of the Galactic Disk
Abstract
After some general remarks on the dynamical evolution of the galactic disk, a review is presented of mechanisms which may affect the velocities of disk stars: stochastic heating, deflections, adiabatic cooling or heating. The observed velocities of nearby disk stars are compared with theoretical predictions based on the diffusion of stellar orbits.
