Description:

Core-collapse supernovae (SNe) are powerful astrophysical explosions that shape their surrounding environments, leaving behind compact remnants. Many of their massive stellar progenitors originate in binary systems, where interactions significantly influence their evolution toward the explosion, observational characteristics, explodability, and timing. In my talk, I will first explore the effects of binary interactions on the statistical properties of stripped-envelope SNe and illustrate how their stellar companions can be used to study these events. Additionally, I will present the predicted population of binary progenitors for the more common hydrogen-rich, Type II SNe, the up-to-date observational evidence for them, and outline a methodology that we put into practice to start identifying them. I will finally show the impact of binary interactions on the timing of SNe and on the so-called 'Red-Supergiant problem'.
