Abstract

The present state of the Galaxy can be idealized as a stellar system with severi components: inner bulge, main bulge, thin disk, thick disk, stellar halo, corona, etc. In the regions where the diffusion phenomena are negligible, the dynamics can be determined from a conservative dynamic system, according to the superposition principle with a common potential. Here we describe the kinematical. behavior of the main bulge, thin and thick disks, and stellar halo, depending on the cylindrical. galactocentric coordinates r and z, under axisymmetric conditions. The angular dependence is treated in the work by Sanz-Subirana & Juan-Zornoza (1992).
