We compiled a catalog of 421 references 12-15mag stars for determining accurate positions of objects in the region of M 31. We also compiled a star chart, which is provided as...

We present an atlas of stellar sight line data from the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite for 287 stars in the Magellanic Clouds, obtained from eight years...

The Extreme Ultraviolet Explorer (EUVE) has been detecting EUV sources since its launch in June 1992. Positions of 540 sources have been made available to the community by the...

Positions and magnitudes were derived for 537 stars in the area of the open cluster NGC 129. Combining these positions with data from the three other sources, proper motions...

A cross-identification of the southern-sky objects with the ROSAT All-Sky Survey (Cat. ) and Parkes-MIT-NRAO (PMN) Radio (5GHz) Survey (Cat. ) yields a list of 642 sources....

Using the data observed with the Photoelectric Astrolabe Mark II (PA II) of the Beijing Astronomical Observatory during the period from Feb. 1992 to Oct. 1993 in San Juan of...

The precise positions and proper motions (J2000.0) of 1535 Basic FK5 (FK4) stars in FK5 system (Cat. ) have been used in the reduction of local vertical monitoring and catalog...

A list of 900 radio sources with positional accuracies better than 0.5" has been prepared from seventeen lists of radio source positions found in the literature. This...

As a pilot survey for the forthcoming 6dF Galaxy Redshift Survey, spectroscopy of galaxies selected in the 1.2 micron J waveband with the DENIS imaging survey was performed at...

Most known extrasolar planets (exoplanets) have been discovered using the radial velocity or transit methods. Both are biased towards planets that are relatively close to their...

We present a catalogue of galaxy structures (groups and clusters) found in an area of 5000 square degrees in the southern hemisphere. The catalogue, which we call the PF...

We reconsidered the previous studies of properties of magnetic stars based on the latest data on average surface magnetic fields of 177 stars. New, corrected results have been...

We use the FUV fluxes measured with the GALEX to study the star formation properties of galaxies collected in the Local Orphan Galaxies catalog (LOG, 2011AstBu..66....1K). Among...

The results of a spectral classification of 257 M stars observed in the Cepheus region are given. Their equatorial coordinates, photographic stellar magnitudes, and spectral...

A 10th list of late-type M and C stars found on plates of the First Byurakan Spectral Sky Survey in the -11{deg}<{delta}<-7{deg} belt within area of about 1070{deg}^2^ is...

We study in detail the properties of the stellar populations of 111 massive [log(M/M_{sun}_) => 10] dusty [far-infrared (FIR)-selected] starburst (SFR/SFRMS > 2) galaxies...

We provide new planetary nebula luminosity function (PNLF) distances to 19 nearby spiral galaxies that were observed with VLT/MUSE by the PHANGS collaboration. Emission line...

In this paper, we present the structural properties and morphology of galaxies in the central region of the Coma Cluster brighter than 19.5 mag in the F814W band from the...

We investigate the temporal and colour variability of 897 blazars, comprising 455 BL Lacertae objects (BL Lacs) and 442 Flat Spectrum Radio Quasars (FSRQs), selected from the...

Due to the high quality of Gaia DR2 stellar parallaxes and proper motions, we can study the Cygnus OB2 region up to G=17.5mag in circular region centred at...
