An upper limit to the local dark matter or the missing missing mass

From a stellar population model based on evolution theory we build a self consistent dynamical model of the Galaxy through the Boltzmann and Poisson equation. We show that comparisons of model predictions with general star counts give strong constraints on the dynamical mass density in the solar neighbourhood. A best fit solution is obtained with a model including a small unseen-mass disc of density. 01 Mopc-3 and 600 pc scale height. The total dynamical mass density in the solar neighbourhood ranges between .09 and .12 Mopc-3. These values are well compatible with published estimation of the observed local mass
