Abstract

The $^{12}$C($^{12}$C,$\alpha _{0,1}$)$^{20}$Ne and $^{12}$C($^{12}$C,$p_{0,1}$)$^{23}$Na reactions, which determine carbon burning in stars, have been measured from E$_{c.m.}$ = 2.7 MeV down to 0.8 MeV via the Trojan Horse Method off the deuteron in $^{14}$N. This range of energies is relevant for several astrophysical scenarios, from superburst ignition to hydrostatic burning. The measured astrophysical S(E) factors reveal several resonances, which are responsible for a very large increase of the reaction rate at the relevant temperatures.
