The catalogue contains observations of the linear polarization in the UBVRI photometric system of 8 Northern Be stars; the observations are part of a long-term monitoring...

H{alpha} photometry is presented for 172 southern F, G, and K type stars, mostly of luminosity classes V and IV. The bands measured, using a spectroscopic resolution of...

The catalog is a compilation of photoelectric photometry obtained as part of a program investigating the distribution of stars and stellar matter perpendicular to the galactic...

This catalog is a compilation of 11206 stars suspected of variability and not finally designated as variables prior to 1997. It is the supplementary part to the "New Catalogue...

The catalogue presents the main data on 1362 extragalactic supernovae (SNe) discovered up to July 13, 1998 and on their parent galaxies. SNe are ordered by Right Ascension of...

Observations are listed in alphabetical order of the constellations. The standard deviation for every magnitude and color is 0.01 mag. Cone search capability for table...

The Catalog of Infrared Observations and its associated data base comprise a summary of infrared astronomical observations published in the scientific literature from 1965...

This catalogue is an updated version of the one published in 1990 (Hauck and Mermilliod, 1990) and contains data for more than 63,300 stars in the Galaxy and Magellanic Clouds....

The GCVS is the only reference source on all known variable stars. This version contains all of the electronically-readable version as distributed by the Sternberg Astronomical...

We present the Catalog of Periodic Variable Stars in the Galactic Bulge. The Catalog is based on observations collected during the OGLE (Optical Graviational Lensing Experiment)...

The survey is a high galactic latitude, large area (552 square arcmin) blank-field sample to a 5{sigma} limit of K=17.3mag. Star-galaxy discrimination is performed. The infrared...

Photoelectric UBV values, derived from observations made at the Boyden and ESO observatories, are presented for 358 early-type stars in the Vela section of the southern Milky...

Deep BVRI CCD photometry was performed on a 1 square degree region of M31. The observations were made between September 12 and September 27, 1990, using the McGraw-Hill 1.3m...

The Palomar-Green Catalogue of UV-excess stellar objects provides positions accurate to about 8arcsec in each coordinate, photographic B-magnitudes accurate to 0.29mag, spectral...

This catalogue is the last volume of the world-only reference source on all known variable stars. It contains the first Catalogue of variable stars in external galaxies as well...

The Extreme Ultraviolet Explorer satellite was launched on June 7, 1992 from Cape Canaveral, Florida on a Delta II rocket. The payload contains three EUV scanning telescopes...

This is the fourth catalogue of photometric data in the Stroemgren system obtained during the period June 18, 1992 - August 23, 1994 in the framework of the Long-Term Photometry...

We present a revised version of "Sternberg Astronomical Institute Supernova Catalogue" which includes data on 930 extragalactic supernovae (SNe) discovered up to September 1,...

This is the third catalogue of photometric data in the Stroemgren system obtained during the period October 1990-January 1992 in the framework of the Long-Term Photometry of...

The relationship between interstellar extinction and distance in the direction of dark clouds in the areas around the open cluster IC 348 and the association Per OB2 is...
