Stars with this element in their atmosphere have a spectra that features Swan bands. A core of oxygenand this element, as well as a helium envelope, is found in stars at the tip of the asymptotic giant branch.White dwarfs that exceed the Chandrasekhar limit due to accretion generally undergo a Type Ia supernovain a detonation named for this element. Only 25 MeV--as opposed to 26.2--of energy is released in a stellarprocess that uses this element as an intermediate and recovers it at the end. That process also uses nitrogenand oxygen as intermediates. This element is formed in the triple-alpha process. For 10 points, identify thiselement with atomic symbol C.
