Fred Hoyle proposed a 7.65 mega-electron-volt resonance in a heavier element as a result of analyzing the stellar fusion of this element. The lack of a spectral line for this element distinguishes Type Ic (one c) supernova from Type Ib (one b). The most prominent spectral line in B-class stars is a spectral line due to the presence of neutral atoms of this element. This element is the heaviest that does not contribute to a star's (*) metallicity. Stars more mass than the Sun can produce this element by cycling from carbon-12 through isotopes of carbon, nitrogen, and oxygen, before landing back on carbon-12. This element was first identified in the emission spectrum of the Sun's chromosphere. It is fused to form beryllium, then carbon, in the triple alpha process. For 10 points, name this fusion product of hydrogen in stars.
