Abstract

Carbon burning is crucial for the fate of massive stars and element creation in the Universe. Its understanding at stellar energies is a great theoretical challenge, as carbon fusion is a multidimensional quantum tunneling process affected by resonances whose origin is not fully understood yet. Simplified quantum dynamical coupledchannels calculations are presented, suggesting that clustering in the intermediate nuclear molecule is a source of fusion resonances. (AU)
