Using the relative proper motions and membership probabilities of 785 stars in the region of the open cluster M 11 (within 25′ of the cluster center), we found for the cluster, a distance of 1659 pc, and an age of (1.8−2.2)×108yr, a radius of ab

From PDS microdensitometer measurements of 10 plate pairs of the open cluster M 11 with epoch differences of 16–70 years taken with our 40 cm double astrograph, the relative proper motions of 872 stars in the cluster region are determined. 85% of t

We study the luminosity and mass functions of the member galaxies in the central 6° of the Virgo Cluster. Membership is determined using velocity as criterion, while giving due consideration to the density distribution. Our study shows that the lumi

Recently available radial velocity data of K-stars are used for an analysis of their kinematics in the solar neighbourhood. Solution for the mean solar motion is u0 = −9.1 ± 2.2, v0 = −20.4 ± 2.6, w0 = −5.2 ± 2.5 km/s, in fair agreement with
