The astrophysical parameters compiled from literature for 809 stars of different types, mainly Population II stars, are presented. The results of classification in the Vilnius...

The open cluster IC1369, located in Cygnus close to the galactic equator at the 89.6{deg} longitude, and its vicinity are investigated by applying two-dimensional photometric...

The dust cloud TGU H645 P2 and embedded in it the young open cluster NGC 7129 are investigated using the results of medium-band photometry of 159 stars in the Vilnius...

The results of medium-band photometry of 1037 stars in the area of the old open cluster NGC 7142 down to V=20.1mag in the Vilnius seven-colour system are presented. Photometric...

Seven-color CCD photometry in the Vilnius photometric system of 279 stars down to V=15mag in the open cluster M 67 area is obtained. 13 standard stars in the cluster are...

Magnitudes and color indices in the Vilnius seven-color system were determined for 1752 stars down to V = 19.5 mag in the direction of the open cluster M29 (NGC 6913). The...

In a 1.5 square degree area, centered at RA=21:44:30, DE=+65:58, we have determined magnitudes and color indices for 2140 stars in the Vilnius seven-color system down to...

We have performed multicolor CCD observations of the central area of NGC 752 to search for faint, low-mass members of this open cluster. Four 12'x12' fields were taken on the...

We present the results of eight-color CCD photometry of 674 stars in the direction of the open cluster Tombaugh 5 in Camelopardalis. The stars are observed in the Vilnius system...

CCD photometry in the eight-color Vilnius + I system for 7250 stars down to I=19.6mag has been obtained in the 20'x26' field of the open cluster IC361 in Camelopardalis. The...

The results of CCD photometry in the seven-color Vilnius system of 3058 stars down to V~18.0mag in a 1.5 square degree field around the cluster NGC752 are presented. For most of...

We present the results of CCD photometry in the seven-color Vilnius system for 1549 stars down to V=16mag in a 1.5 square degree field around the cluster King 7, at the Perseus...

The area of the open cluster NGC 1647 in Taurus is investigated by CCD photometry in the Vilnius seven-color system. Magnitudes and color indices are determined for 433 stars...

The area of the open cluster NGC 2395 in Gemini is investigated by CCD photometry in the Vilnius seven-color system. Magnitudes, color indices, photometric spectral types, color...

Seven color CCD photometry in the Vilnius system, supplemented by the Cousins I passband, has been obtained for 412 stars down to V=16mag in the M67 open cluster area. A special...

Seven-color photometry in the Vilnius system has been obtained for 420 stars down to V=16mag in the area containing the overlapping open clusters NGC 1750 and NGC 1758 in...

A catalog of spectral types, color excesses, interstellar extinctions and distances of 402 stars located in the Serpens Cauda dark cloud complex and the new results of...

Interstellar extinction in two concentric square areas of the sizes 1.25x1.25deg^2^ and 0.2x0.2deg^2^ in the direction of open cluster King7 is investigated applying...

Optical and infrared continuum polarization from the interstellar medium is driven by radiative processes aligning the grains with the magnetic field. While a quantitative,...

We present and analyse photometric and spectroscopic observations of the WN5 star EZ Canis Majoris obtained over a period of 7 years. We discuss the changing light curve, the...
