Abstract: Carbon and oxygen burning reactions, such as 12C+12C, 12C+16O, and 16O+16O are important for late stellar burning phases. The strength of these fusion reactions also determine the ignition, burning, and nucleosynthesis pattern in cataclysmic binary systems such as type Ia supernovae and x-ray super bursts. Various experimental work and developments related to measurement of these reaction rates have been carried out at University of Notre Dame. In particular, 12C+12C and 12C+16O fusion experiments with SAND (a silicon detector array) have been conducted using the high-intensity St. ANA accelerator and particle-gamma coincidence technique. New results on their cross sections at low energies relevant to nuclear astrophysics will be reported. Its impact on the carbon burning process under astrophysical scenarios will be discussed as well.
