    On the evolution of supernova remnants. II - Two-dimensional calculations of explosions inside pre-existing wind-driven bubbles
    Supernova explosions within wind-driven bubbles are studied with 2D hydrodynamical calculations. Two different density distributions for the ejecta are...

    On the fate of the most massive stars
    Radiation-driven mass loss largely determines the life expectancy of massive stars. I will present our most recent mass-loss predictions for massive stars...
  • Publication
    On the formation of massive stellar clusters
    Here we model a star forming factory in which the continuous creation of stars results in a highly concentrated, massive (globular cluster-like) stellar system...
  • Publication
    On the O/Fe versus Fe/H relationship and the progenitors of type I supernovae
    The new observational O/Fe versus Fe/H abundance relationship for halo stars is studied in terms of several models of chemical evolution for the solar...

    On the Progenitor of the Type Ic Supernova 2002ap
    This Letter presents wide-field optical and near-IR (UBVRIHαK') images of the galaxy M74 that were taken between 0.6 and 8.3 yr before the discovery of the Type...

    Optical and infrared photometry of the Type IIn SN 1998S: days 11-146
    We present contemporaneous optical and infrared (IR) photometric observations of the Type IIn SN 1998S covering the period between 11 and 146d after discovery...

    Optical observations of GRB 060218/SN 2006aj and its host galaxy
    The supernova SN 2006aj associated with GRB 060218 is the second-closest GRB-SN observed to date (z=0.033) and is the clearest example of a SN associated with a...

    Optical polarimetric monitoring of the type II-plateau SN 2005af
    Aims.Core-collapse supernovae may show significant polarization that implies non-spherically symmetric explosions. We observed the type II-plateau SN 2005af...

    Optical polarimetry of SN 2004bv
    We report R band imaging polarimetry of SN 2004bv in NGC 6907 on June 19.299 (UT middle of observation), i.e., two weeks after maximum. We have obtained [ 0.11...
