Massive star formation in dwarf Wolf-Rayet galaxies - Angel Lopez-Sanchez colloquium
In this colloquium I present the main results of my PhD Thesis, in which a detailed morphological, photometrical and spectroscopical analysis of a sample of 20 Wolf-Rayet (WR) galaxies was realized. WR galaxies are a subtype of H II galaxies whose integrated spectra show broad emission lines attributed to WR stars, indicating the presence of an important population of massive stars and the youth of the starburst. The main aims are the study of the star formation and O and WR stellar populations in these galaxies and the role that interactions between low surface companion objects could have in the triggering mechanism of the bursts.
