In the classical carbon stars, those belonging to the modern spectral types C-R and C-N, the abundance of carbon is thought to be a product of helium fusion, specifically the triple-alpha process within a star, which giants reach near the end of their lives in the asymptotic giant branch (AGB).

De koolstof in de klassieke koolstofsterren, die behoren tot de moderne (zie beneden) spectraalklassen C-R en C-N, is afkomstig van heliumverbranding, met name het triple-alfaproces binnen de reuzensterren aan het eind van hun leven in de asymptotische reuzentak.
