ABSTRACT A new class of models stellar discs is introduced and used to build a self-consistent model our Galaxy. The defined by the parameters that specify action-based distribution functions (DFs) f(J) four (three thin-disc age cohorts thick disc), spheroidal bulge dark haloes. From these DFs plus specified gas, we solve for densities stars matter potential they generate. principal observation...
