Core-Collapse Supernova Progenitors from Light Curves and Stellar- Evolution Models

Supernovae (SNe) are excellent laboratories for testing many aspects of stellar-
evolution theory with strong implications on many various areas of astrophysics.
Their light curves are extremely sensitive to the properties of their progenitor
stars or systems and their environments. With the increasing amount and improved
quality of current data, new types of SNe or unexpected features in normal
events are being detected. These discoveries challenge our standard knowledge of
how massive stars explode, as well as the mechanisms that power these events. In
this talk I will focus on the modelling efforts that we have been doing in order
to understand the properties of normal and some peculiar objects. In Particular,
I will show our results on a large sample of hydrogen-rich SNe. Our analysis
indicates that most of the SNe II come from relatively low-mass progenitors
(MZAMS < 10 Msun). These results have important implications on our knowledge of
massive-star evolution.

This is a hybrid event. The organiser will support support remote participation over Teams.

The colloquium will be followed by drinks and nibbles.
