NGC 1750 & 1758 membership probabilities
Cluster-field segregation and determination of physical parameters of the open clusters NGC 1750 and NGC 1758 were performed from CCD and photographic photometric and... -
Mass segregation in open clusters
On the basis of the best available member list and duplicity information, we have studied the radial structure of Praesepe and of the very young open cluster NGC 6231. We have... -
Deep UVBRI photometry in IC 348
Table3 contains UBVRI-CCD photometry for the 123 observed stars in the nucleus of IC 348 open cluster. Magnitude and colours are given with their corresponding errors. Column... -
BH 176 and AM-2
We have obtained VI photometry for two low Galactic latitude star clusters: BH 176 and AM-2, using the 2.2m and the 3.5m NTT telescopes at ESO. Their VI colour-magnitude... -
ESO 96-SC04 and ESO 92-SC18 photometry
We present deep CCD BV photometry in the central region of the faint open clusters ESO 96-SC04 and ESO 92-SC18. The color magnitude diagrams (CMD) here presented allows us to... -

Catalog of Stellar Rotational Velocities
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... -
K-Line photometry of stars in Population I clusters
Photoelectric photometry of the K-line of calcium has been performed for the A stars of five open clusters (Hyades, Pleiades, IC 2391, IC 2602, and NGC 6475) and one association... -
Variable stars in the M16-M17 field
The original work was published as a paper book by the Perugia University in 1999. Before that, only the variable stars list (coordinates, classifications, periods, epochs,... -
ISM towards IC 348 and Per OB2
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... -
Photometric study of IC 4665

Tonantzintla Pleiades Flare Stars
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... -
Monitoring low-mass stars in NGC 2362
We report on the results of a time-series photometric survey of NGC 2362, carried out using the CTIO 4-m Blanco telescope and Mosaic-II detector as part of the Monitor project.... -
BVRIc photometry of Stock 8
We present UBVIc CCD photometry of the young open cluster Stock 8 with the aim of studying its basic properties such as the amount of interstellar extinction, distance, age,... -
Proper motions of field L and T dwarfs
The proper motion measurements for 142 previously known L and T dwarfs are presented. From this sample we identify and discuss eight high-velocity L dwarfs. We also find four... -
UBV(RI)c photometry in clusters Tr 1 and Be 11
We present deep UBV(RI)C charge-coupled device (CCD) photometry for the young open star clusters Tr 1 and Be 11. The CCD data for Be 11 are obtained for the first time. The... -
BVI photometry of NGC 2547
We have developed the techniques required to use Naylor's optimal photometry algorithm of to create colour-magnitude diagrams with well-defined completeness functions. To... -
Integrated Spectra of Open Clusters
We present a library of 39 open cluster optical/near-IR integrated spectra. The data were obtained at CASLEO (San Juan, Argentina) and LNA (Itajuba, Brazil). Eight additional... -
Proper motions of field L and T dwarfs
By using images taken with Wide Field Camera (WFCAM) on United Kingdom Infrared Telescope (UKIRT) and Son of ISAAC (SofI) on the New Technology Telescope (NTT) and combining... -
Berkeley 21 BVI photometry
We present CCD BVI photometry of the old open cluster Berkeley 21, one of the most distant clusters in the Galactic anticentre direction, and possibly the lowest metallicity...
