Resum
Solving the Boltzmann collisionless equatio n under the axisymmetric hypot hesis introduces serious lim itations on describing the kinematics of a single stellar system according to the local Galactic observables. Instead of relaxing the hypothesis of axisymmetry, one alternative is to assume a mixture model. For a finite mixture of ellipsoidal velocity distributions, the coexistence of several stellar populations sharing a co mmon potential introduces a set of conditions of consistency that m a...
