    The Hα Emission of the Spiral Galaxy NGC 7479
    We use the catalogue of HII regions obtained from a high quality continuum-subtracted H_α image of the grand-design spiral galaxy NGC 7479, to construct the...

    The Internal Kinematics of Complete Sets of HII Regions in Disc Galaxies
    We analyse spectral images across the full emission line in H_α of the discs of M100 and M101, extracting for each HII region its spectrum, and for the more...

    The Interpretation of a 2175A Absorption Feature in the Gravitational Lens Galaxy SBS0909 + 532 at z = 0.83
    Comparison of recent spectra by V. Motta et al. (V. Motta et al.: Astrophys. J. 574, 719 725) of two images of a distant gravitationally lensed quasar (z = 1.38...

    The Liège Oscillation code
    The Liège Oscillation code can be used as a stand-alone program or as a library of subroutines that the user calls from a Fortran main program of his own to...

    The Local Interstellar Medium in the Direction of the Galactic Anticentre
    High resolution observations of interstellar Na I absorptions in the spectra of early-type stars in the second Galactic quadrant have been used to derive the...

    The Mass Function at the End of the Main Sequence: The M35 Open Cluster
    We present very deep RIc photometry of the M35 open cluster. We have covered 30' \times 30', equivalent to about a fourth of the total area of the cluster. The...

    The Most Luminous Stars in Our Galaxy
    We present quantitative analyses of 7 galactic O stars of spectral types from O3 to O6. By means of classical hydrostatic and planeparallel models we find the...

    The Origin of the Diffuse Hα in Spirals
    Using high-quality H_α images of five spiral galaxies, we have studied the luminosity and distribution of the emission from diffuse ionized gas (DIG). The...

    The Photometric Behaviour of Bh-Virginis
    Visible light curves of the RS CVn short-period system BH Vir, collected over 26 years, have been analyzed.B-V colours indicate that the primary minimum is...
