PublicaciónNo Surviving Companion in Kepler's Supernova
We have surveyed Kepler’s supernova remnant in search of the companion star of the explosion. We have gone as deep as 2.6 L ⊙ in all stars within 20% of the...

PublicaciónOn 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...

CharlaOn 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...

PublicaciónOn 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...

PublicaciónOn 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...

PublicaciónOn 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...
