<prompt> Isigaba: Isigaba sika-Vega siwu-A0V, okwenza kube yinkanyezi emhlophe enemibala eluhlaza okwesibhakabhaka ehlanganisa i-hydrogen ne-helium emgodini wayo. Njengoba izinkanyezi ezinkulu kakhulu zisebenzisa uphethiloli wazo wokuhlanganiswa ngokushesha kunezinkanyezi ezincane, isikhathi sokuphila se-Vega esiyinhloko-inqubo yokuhlanganiswa cishe iminyaka eyizigidi eziyinkulungwane, ingxenye yeshumi yeLanga. Iminyaka yamanje yale nkanyezi ingeminyaka engaba yizigidi ezingama-455 ubudala, noma cishe isigamu sesikhathi sokuphila kwayo esiphelele esilindelekile. Ngemuva kokushiya ukulandelana okuyinhloko, iVega izoba yisigaba-M esibomvu futhi ekugcineni ilahle iningi lesisindo sayo, ibe yi-dwarf emhlophe engu-3.6M. Njengamanje, iVega inesisindo esingaphezu kokuphindwe kabili seLanga kanye ne-bolometric luminosity yayo cishe izikhathi ezingama-40 zeLanga.  <response>: isidudla esimhlophe
