    Correlations between Structural Parameters of Disk Galaxies
    We have obtained (in BVRI filters) the structural parameters of four disk galaxies, spanning a range of different morphological types. We believe the parameters...

    Data acquisition interfaces for GHRIL ITV-IPD detectors
    So as to meet the requirements of high spatial resolution techniques, two data acquisition interfaces for ITV and IPD detectors have been developed. These...

    Decay rates of sunspot groups from 1874 to 1976
    The global behaviour and fine structure of the distribution of sunspot decay rates from activity cycle 13 to 20 are presented. It is shown that the distribution...

    Deriving Star Formation Histories: Evolutionary or Population Synthesis Codes versus Color-Magnitude Diagrams
    The goal of this project is to analyze the integrated-light spectrum of a region in the LMC bar, for which HST images are already available yielding color...

    Evolutionary Stellar Population Synthesis at 2 Å Spectral Resolution
    I present an evolutionary stellar population synthesis model which predicts spectral energy distributions, SEDs, for simple old single-metallicity stellar...

    Faint Features of Interacting Galaxies Revealed by the Digital Coaddition of 13 Tech-Pan Films of the Virgo Cluster
    We have digitally coadded APM scans of 13 Kodak TechPan films of the SE region of the Virgo Cluster of galaxies. The ~6.2°×6.2° field of the R-band films...

    First Results from ROTES: The ROtse Telescope Eclipsing-binary Survey
    Detached eclipsing binaries (EBs) provide a unique opportunity to carry out stringent tests on stellar evolution models. The value of EBs is enhanced by their...

    First results from the POMME survey of M31
    The POMME survey (Pixel Observations of M31 with MEgacam) monitored two fields in the disc of M31 using MegaCam at CFHT over a timespan of 2.5 months in three...
