The ¹²C + ¹²C Reaction Rate and the Explodability of Core Collapse Supernovae

Reaction rates have a very strong impact on the evolution of stars. Therefore, they can also change the thermodynamic structure of massive stars before the onset of collapse. We present the results of supernovae simulations for stars with masses from 12 to 28 solar masses evolved using the reaction rate for ¹²C + ¹²C fusion from Caughlan & Fowler (1988) and the one from Tumino (2018). We show the impact of this rate on the final explodability as a function of progenitor mass. In addition to that, we show that the explosion of the supernova is only sensitive to the entropy and density profile before collapse. Therefore, if a change in the reaction rate changes the density and entropy profiles before collapse, it can also affect the explodability as a function of progenitor mass.
