    2.2 micron stellar counts at the galactic plane.
    The author presents 2.2 micron maps of selected areas of the galactic plane, taken with the 1.5 m. Sánchez-Magro telescope on the island of Tenerife. A model of...

    A cold massive interstellar cloud within 120 parsecs of the Sun: K I optical and H I radio observations
    We first discovered the presence of a particularly massive cloud in the neighborhood of the Sun, close to the Galactic plane in the direction of Perseus, toward...

    CCD UBVR photometry of the old rich open cluster King 2 - Comparison with theoretical models
    In this paper we present the Johnson-Cousins UBVR CCD photometry of the stars in King 2, an old open cluster towards the galactic anticenter. We have obtained...

    Condensation of dust around the Wolf-Rayet star WR 125
    Infrared photometry of the WC7-type Wolf-Rayet star WR 125 (MR 93) in 1981-91 shows a 10-fold rise in the 3-4 micron flux during 1990-91. This, together with...

    Correlation of broad and narrow diffuse band features Evidence for molecular carriers
    Spectra of early-type stars in several heavily reddened OB associations are used to study broad diffuse bands in the range from 5700 to 6300 angstroms. The...

    Deep CCD photometry of stars in the globular cluster M3
    CCD photometry of faint stars in the globular cluster M3 is presented. The observations reach down to V equal to about 23 mag, with a sample of approximately...

    Dust extinction in NGC 4594, the Sombrero galaxy
    The extinction law in the well-defined dust lane of the Sombrero galaxy, NGC 4594, was studied. In the R, I, J, H, and K bands good agreement is found between...
