A Simplified Approach to Kinematics of Stars in Solar Neighbourhood
For a number of stars from the Solar neighbourhood the eccentricities of
their galactocentric orbits are calculated by using a simplified procedure
given by Ninkovic (2011). Eccentricities are calculated from the
three-dimensional orbits around the centre of the Milky Way for the same
sample of stars, by applying a model with the analytically given
gravitational potential as well. The orbital eccentricities (radial span of
each star) obtained in these two manners show a satisfactory agreement. It
can be concluded that for typical thin-disk stars the use of such a
simplified procedure, which requires much less computing time per star, in
determining their motion around the Galactic centre is justified. [Projekat

期刊介绍：
Serbian Astronomical Journal publishes original observations and researches in all branches of astronomy. The journal publishes:
Invited Reviews - review article on some up-to-date topic in astronomy, astrophysics and related fields (written upon invitation only),
Original Scientific Papers - article in which are presented previously unpublished author''s own scientific results,
Preliminary Reports - original scientific paper, but shorter in length and of preliminary nature,
Professional Papers - articles offering experience useful for the improvement of professional practice i.e. article describing methods and techniques, software, presenting observational data, etc.
In some cases the journal may publish other contributions, such as In Memoriam notes, Obituaries, Book Reviews, as well as Editorials, Addenda, Errata, Corrigenda, Retraction notes, etc.
