About article:
In a study of the Oort-Cloud dynamics, stellar perturbations should
system has to reflect both the frequency and perihelion distribution
of passing stars at the same time. We provide such a model for a 1 Gyr
period assuming the same Galactic environment in a solar vicinity as it is
nowadays for the entire period. The modelling includes the determination
of a critical distance within which all stars of a given spectral type
should be considered. The resultant data comprise the dynamical
characteristics of 41 589 simulated stars passing the solar system
over 1 Gyr. These data are available in an electronic form at
http://www.ta3.sk/caosp/Eedition/FullTexts/vol37no3/pp161-172.dat/.
Moreover, we demonstrate that the influence of the Galactic tide on
the heliocentric trajectories of the stars, when they perturb the
Oort-Cloud comets, can reliably be neglected.
