4. 12C and 16O: keys to the advanced phases of massive stars evolution

Dr Thibaut Dumont (IPHC Strasbourg)

Nuclear reactions involving $^{12}$C and $^{16}$O are key for the chemical evolution of massive stars during their advanced burning phases. These reactions shape the stellar structure, the evolution up to the pre-supernova stage and, ultimately the nature of the compact remnant.

In this talk, I will present our work exploring the impact and consequences of different nuclear reaction rates...

30. The impact of the carbon fusion rate for superbursts

Superbursts are very energetic explosions occurring at the outer crusts of neutron stars, as a consequence of unstable carbon burning . They release up to $10^{40}$ erg in a span of hours/days and have recurrence times in the order of years. In contrast to the standard, less-energetic bursts due to H/He burning, only a few multi-zone simulations have been reported. While these pioneering works...
