The catalog is a compilation of cross-identifications between the numbering system of Mermilliod (1978) for stars in open clusters and the numbering systems of several other...

This compilation contains more than 5700 individual radial velocities for 370 stars in 4 open clusters. Cone search capability for table III/55/catalog (The compilation)

The results of the spectral classification of 1224 O-M stars of different luminosity classes in the region of NGC 2175 and around it are presented. The classification has been...

The catalog is a compilation of the observed projected rotational velocities, V_rot_sin(i), for 28179 stars from 166 open clusters, globular clusters and associations. The...

The original catalog lists the flare stars discovered by different astronomical observatories over an area slightly larger than 20 square degrees in the Pleiades regions...

We have carried out Wide Field Planetary Camera 2 V- and I-band imaging of the young LMC cluster NGC 2157. Construction of a color-magnitude diagram and isochrone fitting yield...

Mean proper motions and parallaxes of 205 open clusters were determined from their member stars found in the Hipparcos () Catalogue. 360 clusters were searched for possible...

The understanding of the accretion process has a central role in the understanding of star and planet formation. We aim to test how accretion variability influences previous...

In the last 15 years different ground-based spectroscopic surveys have been started (and completed) with the general aim to deliver stellar parameters and elemental abundances...

MWSC-e14a ("MWSC extension 2014a") is a catalogue of 139 new open clusters at high Galactic latitudes (\|b\|>20 deg) including lists of candidate members. It extends the...

MWSC presents a list of 3006 Milky Way Stellar Clusters (MWSC), found in the 2MAst (2MASS with Astrometry) catalogue. The target list was compiled on the basis of present-day...

MWSC presents a list of 3006 Milky Way Stellar Clusters (MWSC), found in the 2MAst (2MASS with Astrometry) catalogue. The target list was compiled on the basis of present-day...

An investigation on dust properties in the NW portion of NGC 6611 has been conducted polarimetrically to test the existence of abnormal extinction in that section of the open...

Near infrared imaging observations in JHK broad bands and H_2_ v=1-0 S(1) narrow band of the star formation region GGD12-15 are presented in this article. The images reveal...

UBVRI and H{alpha} CCD photometry has been obtained for the young open cluster NGC 6231. From the R-H{alpha} color, a measure of the H{alpha} emission, we find 12...

Results of photoelectric UBVRI photometry of 78 stars and photographic PDS and CCD photometry for 437 stars are presented for Collinder 110, an old open cluster at low Galactic...

Colour-magnitude diagrams are presented for the first time, of the faint southern star cluster UKS 2, which was for a long time reported as a globular cluster candidate. The V...

CCD photometry of the northern open star cluster NGC 7790 has been carried out in BVI photometric passbands down to V~21mag for 1150 stars of which for ~700 stars, the data is...

The Orion Nebula is one of the best-studied star-forming regions in our Galaxy and provides an ideal laboratory to study the early stages of star formation. Understanding the...
