Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Muzvokuongorora nyeredzi, zvinhu izvo zvine nhamba dzeatomu dzakakwirira kupfuura helium zvinonzi "zvinhu zvesimbi". Metallicity yephotosphere yeVega inongova 32% chete yeuwandu hwezvinhu zvinorema mumhepo yeZuva. (Enzanisa ikoku, somuenzaniso, nokuwanda kwesimbi katatu mu Sirius yakafanana nenyeredzi kana ichienzaniswa neZuva.) Kuenzanisira, Zuva rine zvinhu zvakawanda zvinorema kupfuura helium zvinenge ZSol = 0.0172 ± 0.002. Nokudaro, maererano nokuwanda, inenge 0.54% chete yeVega ine zvinhu zvinorema kupfuura helium.  Mubvunzo: Zvinhu zvingani zvinorema kupfuura helium zviri muVega?
