A magnitude-limited photographic survey of relative proper-motion components and B, V photometry of 1.3x10^6^ stars brighter than apparent B magnitude 14.5+/-0.5 in the fourth...

We use very long baseline interferometry data obtained between mid-1995 and the end of 2002 May together with older data to extend and revise the International Celestial...

This paper presents new positions for 689 FK5 stars determined directly in the extragalactic reference system from CCD scan observations made with the Flagstaff Astrometric...

Proper motion stars have been identified from red IIIaF ESO Schmidt plates. This catalogue includes stars found in ESO Areas 207, 439, and 440 having mu >= 0.1 arcsec/yr....

BVR photoelectric photometry and positions are reported for 437 stars in 49 Palomar Sky Survey fields. A relation is derived between the Johnson BVR photometry and the E and O...

The positions in right ascension and declination of 1105 FK5 stars, observed with a Meridian Circle during the period 1979 to 1991, are given. The average mean square error of a...

This catalog contains optical positions of 221 radio stars observed with the Bordeaux automatic meridian circle. The observations were strictly differential, a convenient number...

The Photoelectric Astrolabe Mark I (PHA I) has been revised with a new combined prism which could work as an almucantar with zenith distance of 45 degree, to measure continuous...

The positions of 53 FK5, 70 FK5 Extension and 486 GC stars are given for equator and the equinox J2000.0 and for the mean observation epoch of each star which are determined...

We have developed a procedure (so called PAPA) for measurement of magnitudes (about 0.1mag accurate) and positions (with accuracy better than 0.5arcsec) of all the objects...

The paper contains 515 individual corrections {DELTA}{alpha} and 235 corrections {DELTA}{delta} to FK5 and FK5Supp. stars and 50 corrections to their proper motions computed...

UBVRI photometry in the Kron-Cousins system was observed for 117 stars of the Catalogue of Fundamental Faint Stars (FKSZ stars) in the declination zone 0 to +18{deg}. The...

Supernova feedback injects energy and turbulence into the interstellar medium (ISM) in galaxies, influences the process of star formation and is essential to understanding the...

Herschel operated as an observatory, therefore it did not cover the whole sky, but still observed ~8% of it. The first version of an overall Herschel/PACS Point Source Catalogue...

Large spectroscopic surveys devoted to the study of the Milky Way, including Gaia, use automated pipelines to determine the atmospheric parameters of millions of stars. The Gaia...

The New Astrometric Reduction of Old Observations (NAROO) program is dedicated to the measurement of astrophotographic plates and the analysis of old observations for scientific...

With an unprecedented astrometric and photometric data precision, Gaia EDR3 provides, for the first time, the opportunity to systematically detect and map, in the optical bands,...

In the era of large surveys and space missions, it is necessary to rely on large samples of well-characterized stars for inter-calibrating and comparing measurements from...

The star cluster R136 inside the Large Magellanic Cloud hosts a rich population of massive stars, including the most massive stars known. The strong stellar winds of these very...

We present the third data release (DR3) of the X-shooter Spectral Library (XSL). This moderate-high resolution near-UV to near-IR (350-2480nm, R~10000) spectral library is...
