Stäckel-type dynamic model of the Galaxy based on maser kinematic data

A dynamic model of the Galaxy is constructed based on kinematic data for masers with trigonometric parallaxes. Maser data is used to compute the model potential in the Galactic plane. The potential is then generalized to three dimensions assuming the existence of a third quadratic integral of motion. The resulting Galactic model potential is of Stäckel's type. The corresponding space density function is determined from Poisson's equation.

On the possibility of applying the quasi-isothermal Stäckel's model to our Galaxy

An earlier derived quasi-isothermal Stäckel's model of mass distribution in stellar systems and the corresponding formula for space density are applied to our Galaxy. The model rotation curve is fitted to HI kinematical data. The structural and scale parameters of the model are estimated and the corresponding density contours for our Galaxy are presented.
