<prompt> Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu: Passage: Rudzi rwomumvuri rwaVega ndiA0V, runoita kuti rive nyeredzi yerondedzero huru yakachena ine ruvara rwebhuruu iyo iri kubatanidza hydrogen kuti ive helium mukati mayo. Sezvo nyeredzi dzakakura zvikuru dzichishandisa mafuta adzo anogadzirwa nokukurumidza zvikuru kudarika duku, upenyu hwaVega hwomutsetse mukuru hunenge makore ane bhiriyoni rimwe, chegumi cheZuva. Zera razvino renyeredzi iyi rinenge makore ane mamiriyoni 455, kana kuti kusvika kuhafu yenguva yaro yose inotarisirwa youpenyu hwomutsetse mukuru. Pashure pokusiya nhevedzano huru, Vega ichava hofori tsvuku yekirasi-M uye icharasikirwa nechikamu chikuru chehuremu hwayo, pakupedzisira ichiva hanyanisi chena. Pari zvino, Vega ine uremu hunopfuura hweZuva nekaviri uye kupenya kwayo kunenge kwakapetwa ka40 kweZuva. Nemhaka yokuti iri kutenderera nokukurumidza uye inoonekwa inenge iri pamhenderekedzo yegungwa, kupenya kwayo kunooneka, kwakaverengwa tichifungidzira kuti kwakanga kwakaenzana kwose kwose, kwakapetwa kanenge ka57 kweZuva. Kana Vega ichichinja-chinja, ipapo ingava yerudzi rweDelta Scuti ine nguva yemazuva anenge 0.107. Simba rakawanda rinogadzirwa mukati meVega rinogadzirwa necarbonnitrogenoxygen cycle CNO cycle, chiitiko chekubatanidza nyukireya chinobatanidza mapurotoni kuti aumbe helium nuclei kuburikidza nepakati nyukireya yecarbon, nitrogen, uye oxygen. Maitiro aya anoda tembiricha inosvika mamiriyoni gumi nemashanu eK, iyo yakakwirira kudarika tembiricha yepakati peZuva, asi haina kunyatsoshanda kudarika proton-proton chain reaction fusion reaction yeZuva. Denderedzwa reCNO rinonzwa zvikuru tembiricha, izvo zvinoguma nenzvimbo yekubvongodzwa pamusoro penzvimbo iyo inoparadzira zvakaenzanamadota kubva pakupindirana kwekupindirana mukati menzvimbo yenzvimbo. Mamiriro okunze ari pamusoro apa ari muenzanisiro yokuparadzira mwero. Izvi zvinopesana neZuva, iro rine nharaunda yemwaranzi iri pakati nepakati nenzvimbo inopfuura. Kuyerera kwesimba kunobva kuVega kwakanyatsoyerwa zvichienzaniswa nemanyuko echiedza akajairika. Pana 5480 Å, kuyerera kuri 3,650 Jy nemuganhu wekukanganisa we 2. Chiratidziro chemuchadenga cheVega chinotungamirirwa nemitsetse yokunyura kwehydrogen; zvikurukuru nemitsetse yeBalmer yehydrogen ine elektroni iri panhamba huru yequantum n2. Mitsetse yezvimwe zvinhu iri... Mubvunzo: Vega ichava chii munguva yemberi?  <response>: chikara chena
