Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: Vega ta spectral class ne A0V, sa shi a blue-tinted fari babban jerin star cewa ne fusing hydrogen zuwa helium a cikin core. Tun da manyan taurari suna amfani da makamashin haɗarsu da sauri fiye da ƙananan, rayuwar Vega ta babban jerin kusan shekaru biliyan ɗaya ne, kashi ɗaya cikin goma na Sun. Shekaru na yanzu na wannan tauraron yana da kimanin shekaru miliyan 455, ko kuma kusan rabin rayuwarsa ta gaba ɗaya. Bayan barin babban jerin, Vega zai zama babban jan giant na aji-M kuma ya zubar da yawancin nauyinsa, a ƙarshe ya zama farin dwarf. A halin yanzu, Vega yana da fiye da sau biyu na taro na Sun kuma haskensa na bolometric shine kusan sau 40 na Sun. Saboda yana juyawa da sauri kuma ana ganin kusan gefen gefen, haskensa na bayyane, wanda aka lissafa yana zaton yana da haske iri ɗaya a ko'ina, kusan sau 57 ne na Rana. Idan Vega mai canzawa ne, to yana iya zama nau'in Delta Scuti tare da tsawon lokaci na kimanin kwanaki 0.107. Yawancin makamashin da aka samar a cikin zuciyar Vega an samar da shi ta hanyar carbon<unk>nitrogen<unk>oxygen cycle (CNO cycle), tsarin hadawar nukiliya wanda ya hada protons don samar da kwayar helium ta hanyar tsaka-tsakin kwayar carbon, nitrogen, da oxygen. Wannan tsari yana buƙatar zafin jiki na kimanin miliyan 15 K, wanda ya fi ƙarfin zafin jiki na Sun, amma ba shi da tasiri fiye da hasken rana na proton-proton chain reaction fusion reaction. Tsarin CNO yana da matukar damuwa da zafin jiki, wanda ke haifar da yankin haɗuwa a kusa da tsakiya wanda ke rarraba 'garwashin' daga halayen haɗuwa a cikin yankin tsakiya. Yanayin da ke sama yana cikin daidaituwa na radiation. Wannan ya bambanta da Sun, wanda ke da yankin radiation wanda ke tsakiyar tsakiya tare da yankin haɗuwa. An auna ma'aunin makamashi daga Vega daidai da tushen haske na yau da kullun. A 5480 Å, gudana shine 3,650 Jy tare da kuskuren kuskure na 2%. Hasken gani na Vega ya mamaye layin sha na hydrogen; musamman ta hanyar jerin Balmer na hydrogen tare da lantarki a n = 2 babban lambar lamba. Lines na sauran abubuwa ne...  Tambaya: Menene Vega zai zama a nan gaba?
