| Summary: | Using the data from the Gliese-Jahreiss Catalogue and a particular form of
the galactic potential the authors construct galactocentric orbits for nearby
stars. The potential used in our paper is stationary and axially symmetric
with three contributors - bulge, disc and dark corona. In the calculating of
the galactocentric phase coordinates the distance of the Sun to the galactic
plane is neglected, the asymmetric drift is not, whereas the components of
the solar motion are varied; the distance of the Sun to the axis of galactic
rotation and the corresponding value of the circular velocity are assumed
according to the model used in the paper. The obtained orbits (projection on
meridional plane) in a vast majority are box-like, or more precisely
trapezium-like. The effect of the assumed solar motion is discussed and
comparisons with results obtained by applying different potentials and
initial conditions are made. |
