<prompt> 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 zvine nhamba yeatomu yakakura kupfuura yehelium zvinonzi chii?  <response>: simbi
