    How to use the SEDs produced by synthesis models (inside and outside the VO)?
    In this contribution we investigate how to describe the results and usage of evolutionary synthesis models. In particular, we look for an explicit and...

    HST emission line images of the Orion HII region: proper motions and possible variability
    The Orion Nebula (NGC 1976, M42) contains the nearest massive star forming region and is therefore ideal for studying the physical process accompanying star...

    HST-NICMOS Observations of Galactic Bulges: Red Nuclei in Nearby Galaxies
    We describe multi-color observations with NICMOS and WFPC2 of 20 nuclei of nearby galactic bulges of types S0-Sbc. We find that the centers of 19 out of 20...

    Hunting for binary central stars of planetary nebulae: exploiting archival data
    The detection of new binary central stars of planetary nebulae is crucial to definitively determine the importance of binary interactions in the nebular...
