We present CCD BVI photometry for the southern open cluster NGC 2489 and its surrounding field. The sample consists of 2182 stars measured in an area of 13.6 × 13.6 arcmin2, extending down to V ∼ 21.5. These data are supplemented with CORAVEL radi

In the course of a long-term radial velocity survey of about 100 southern pre-main-sequence (PMS) stars, we have discovered two spectroscopic PMS binaries. One is the weak-lined T Tauri star Haro 1-14c in the Ophiuchus clouds, which has a spectral ty

We have analysed the binarity and multiplicity characteristics of 120 O-type stars in 22 very young open clusters and found marked differences between the “rich” (N ≥ 6 O-type stars and primaries) and “poor” (N = 1) clusters. In the rich cl

We present the results of a lithium study of the 220 Myr old cluster NGC 6475. Our data are merged with those from previous Li surveys of this cluster in order to construct a more statistically significant sample. The Li vs. effective temperature dis

We present an overview and statistical analysis of the data included in WEBDA. This database includes valuable information such as coordinates, rectangular positions, proper motions, photometric as well as spectroscopic data, radial and rotational ve

We have carried out a high resolution spectroscopic survey of the 220-250 Myr old cluster NGC 6475: our main purpose is to investigate Li evolution during the early stages of the Main Sequence. We have determined Li abundances for 33 late F to K-type

The available evidences for the frequency of binaries in clusters and for nearby and halo field stars are reviewed. More emphasis is given to the star-forming regions and star clusters, which have been surveyed in the past years with various techniqu
