The goal of this dissertation is to determine values of local dynamical
constants. This goal is achieved through examination of multiple samples of selected
stars near the Sun. The selection is done by using planar and vertical eccentricities
as sampling criteria. The solution for calculating eccentricities is given. In the next
step a large sample of stars is selected by defining upper limits for eccentricities and
vertical amplitude. Then nested subsamples are formed in two ways: in the first
one upper eccentricity limit is subjected to decreasing, in the other one this is the
case with upper amplitude of oscillations perpendicular to the plane. The values of
the local dynamical constants are deduced by analysing this material.
