- Description:
- We present the results of CCD photometry in the seven-color Vilnius system for 302 stars in the 12x12 arcmin area in the vicinity of the dark cloud TGU H942 P7. Observational data were obtained in 2015-2016 with the 1.8m VATT telescope of the Vatican observatory on Mt Graham, Arizona. Using the Koenig & Leisawitz (2014ApJ...791..131K) classification scheme we identified 88 YSOs in this area. The majority of them are concentrated in dust clump P7 and the infrared cluster FSR 655. The other compact group of YSOs is located at RA=03:54:56, DEC=+53:45. These stars are probably members of small infrared cluster which we call SCB1.

- Description:
- New photometric observations of the Wolf-Rayet binary HD 211853 are presented. They were obtained with the 1-m reflector of the Institute of Theretical Physics and Astrophysics of the Lithuanian Academy of Sciences on Maydanak Mountain in Uzbekistan during 15 nights in August 1991; a single-channel photometer equipped with the Vilius photometric system filters was used. The period search routine confirms the period of 6.6884 days for pair A. For pair B, a new corrected ephemeris (T0 = 2443689.16, P = 3.4696 days) is determined. This ephemeris allows to present light minima of all available photometric data in the same phase. Moreover, they are in good accordance with the absorption lines radial velocity residuals of Hiltner (1945ApJ...101..356H) and Massey (1981ApJ...244..157M). It is shown that the third possible period of 2.34607 days found by Panov & Seggewiss (1990A&A...227..117P) is an alias from the half period of approximately 3.47 days.

- CDS
- Description:
- The results of CCD photometry in the Vilnius seven-color system down to V=18mag are presented for 242 stars in the direction of the young open cluster IC 1805 that is located in the active star-forming region W4 in the Cas OB6 association. Photometric data were used to classify stars into spectral and luminosity classes, and to determine their interstellar reddenings, extinctions and distances.

- Publisher:
- CDS
- Description:
- 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 region is centered at RA=20:24, DEC=+38:30 (J2000) and covers an area of 1.5 sq. deg. The photometric data are used to classify about 70% of stars in spectral and luminosity classes and peculiarity types.

- Vilnius photometry of NGC 1647 area
- Short Name:
- J/BaltA/14/179
- Date:

- Publisher:
- CDS
- Description:
- 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 down to V=15.0mag in the 45arcmin diameter area. For 252 of them photometric spectral and luminosity classes, interstellar reddenings, extinctions and distances are obtained. According to the CDS WEBDA database, 89 of them have a high cluster membership probability. Their mean distance from the Sun is 555+/-74pc, excluding four stars which seem to be field stars. The main sequence starts at spectral class B7 V which corresponds to a cluster age of about 150 million years. Cluster members show a differential interstellar extinction ranging from 0.8 to 1.8mag. The mean extinction of the cluster stars is 1.12+/-0.25mag. Interstellar extinction in the area is dominated by the Taurus dark cloud complex at 160pc. Color excesses of individual stars correlate well with the 100um dust thermal emission intensity. The cluster shape is investigated by counting stars down to K=15.6mag and is found to be elongated in the direction roughly perpendicular to the Milky Way, with the flattening 0.4.

- Description:
- Photoelectric seven-color photometry in the Vilnius medium-band system has been obtained for 374 stars in four MEGA proper-motion fields, KA 112, KA 113, KA 118 and KA 119, each of about 1.4 square degree size, near the North Galactic Pole. The catalog of observations is complete down to nearly V=13.0mag, except for the one field, KA 118, for which the completeness is achieved down to only V=12.5mag.

- Description:
- The results of CCD photometry in the seven-color Vilnius system are given for 727 stars down to V~17 mag in a 1.5 square degree field in the region of dark cloud TGU H994 P1 (or LDN 1399, LDN 1400 and LDN 1402) in Camelopardalis. Using the intrinsic color indices and photometric reddening-free Q-parameters, two-dimensional spectral types for 73% of stars are determined.

- Description:
- The results of CCD photometry in the seven-color Vilnius system are given for 855 stars down to V~20mag in three 12x12 arcmin areas of the dark cloud TGU H994P1. Observational data were obtained in 2014-2015 with the 1.8m VATT telescope of the Vatican Observatory on Mt Graham, Arizona. Two-dimensional classification in the MK system is given for about 65% of stars.

- Description:
- CCD observations of the northern globular cluster M 92 were obtained in the PXYVS colors of the Vilnius photometric system. The results for 230 stars in an area centered on the cluster and for 178 stars in an area west of the cluster down to V=17.0mag are presented. After a brief outline of the data pathway from observations to reduction via IRAF and a discussion of the photometric errors, the [Fe/H] ratio of the globular cluster M 92 is determined by multicolor PXYVS Vilnius photometry.
