Question

Puffs of this element condensing around R Coronae Borealis stars cause them to decrease in luminosity by up to eight magnitudes at irregular intervals. This element makes up the majority of MAONs (“M-A-O-Ns”) and other compounds that are thought to be the source of so-called “unidentified infrared emission features.” Classifications of stars rich in this element (10[1])typically include a number indicating the intensity of the Swan bands. (10[3])The (10[1])existence (10[1])of a 7.65 MeV (“M-E-V”) excited state of this element (10[1])with angular momentum and parity 0+ (“zero-plus”) was first predicted by Fred Hoyle. (-5[2])Oxygen and this element (-5[1])are the main components of the cores (10[1])of asymptotic giant branch stars. (10[1])Diffuse interstellar bands (10[1])likely originate from compounds with large amounts of this element, such as PAHs (“P-A-Hs”) and (10[2])fullerenes. (10[4])For (10[1])10 (10[1])points, (10[1])name (10[1])this element that is created (10[1])in the triple-alpha process through the fusion of three (10[1])helium atoms. ■END■ (10[2])

ANSWER: carbon [or C] (MAONs are mixed aromatic-aliphatic organic nanoparticles. PAHs are polycyclic aromatic hydrocarbons.)
