    Physical limits to the validity of synthesis models. The Lowest Luminosity Limit
    In this paper we establish a necessary condition for the application of stellar population synthesis models to observed star clusters. Such a condition is expressed by the requirement that the total luminosity of the cluster modeled be larger than the contribution of the most luminous star included in the assumed isochrones, which is referred to as

    Optical spectroscopy of microquasar candidates at low Galactic latitudes
    We report optical spectroscopic observations of a sample of 6 low-galactic latitude microquasar candidates selected by cross-identification of X-ray and radio point source catalogs for |bII | ≤ 5 °. Two objects resulted to be of clear extragalactic origin, as an obvious cosmologic redshift has been measured from their emission lines. For the rest

    Optical observations of space debris in GEO and in highly-eccentric orbits
    The space debris population in low Earth orbits (LEO) has been extensively studied during the last decade and reasonable models covering all size ranges were produced. Information on the distribution of objects in the geostationary ring (GEO), however, is still comparatively sparse. Until quite recently the population of man-made objects in GEO had

    On the Purity of the ZZ Ceti Instability Strip: Discovery of More Pulsating DA White Dwarfs on the Basis of Optical Spectroscopy
    We report the discovery of two new ZZ Ceti pulsators, LP 133-144 and HE 1258+0123, selected on the basis of model atmosphere fits to optical spectroscopic data. The atmospheric parameters for LP 133-144 (Teff=11,800+/-200 K and logg=7.87+/-0.05) and for HE 1258+0123 (Teff=11,410+/-200 K and logg=8.04+/-0.05) place them within the empirical

    On the presence of thermal Sunyaev-Zel'dovich induced signal in the first-year WMAP temperature maps
    Using available optical and X-ray catalogues of clusters and superclusters of galaxies, we build templates of thermal Sunyaev-Zel'dovich (tSZ) emission as they should be detected by the WMAP experiment. We compute the cross-correlation of our templates with WMAP temperature maps, and interpret our results separately for clusters and for

    New Results on Age, Activity and Chemical Composition of the Open Clusters NGC 2451 A and B
    We have conducted a detailed study of the open clusters NGC 2451 A and B which are located along the same line of sight at 206pc and 370pc distance respectively. Although belonging to the nearest clusters they have not been much investigated until present due to strong contamination by field stars. ROSAT X-ray observations and optical UBVR
