Observational diversity of hydrogen-rich supernovae
ABSTRACT:
Type II Supernovae (SNe) II are produced by the final explosions of massive stars (>8 Msun), which retain a significant part of their hydrogen envelopes before the explosion. These SNe show a large diversity in their transient behaviour, which is likely determined by differences, not just in explosion properties, but also in the progenitor star characteristics. In this talk, I will present the current status of SN II studies, in particular, the results of the analysis of a sample of SNe II occurring within low-luminosity galaxies. I will also describe the challenges in the determination of the explosion and progenitor parameters for these objects, and how this scenario is changing thanks to the discovery of new peculiar objects.
