Uhlelo lwe-Unicorn Dual U-U (U M Mon) luseminyakeni engu-3600 elula futhi lufaka izinkanyezi ezimbalwa ezenza ithuba eliphelele elizungeze isikhungo sezinqwaba ezingaba ngu-6.5 ngonyaka wethu. Enye yezinkanyezi yi-supergigant ephuzi ephuzi enobukhulu obuningi cishe buningi ilanga elinesisindo esiphindwe kabili kuphela. Ujabule njalo, wabe esekhula, bese ecindezela esikalini sezinyanga ezintathu. Inkanyezi isho okuguquguqukayo kohlobo lwe-RV Taurus - olunye lwamakhulu ambalwa alutholwa kuyo yonke iMilky Way.
Umngane wakhe ku-U M Mon usizwa kabi; Kucatshangwa ukuthi le nkanyezi iphansi, yize inobukhulu obufanayo futhi ihlala ingu-RV Taurus efanayo. Zizungezwe yidiski ye-gaspile yento ekhipha zombili izinkanyezi noma ezindala kuphela ". Lolu hlelo olungajwayelekile lunikelwe emsebenzini omusha weLaura Vega (uLaura Vega) ovela eNASA kanye nozakwabo, i-athikili ishicilelwe kwi-Astrophysical Journal.
Ababhali baqoqa imininingwane eminingi ebanzi, kufaka phakathi idatha yohlanga kusuka ezithombeni zokuqala ze-UM Mon, eyenziwe ngasekupheleni kwekhulu le-XIX, futhi kuze kube sekupheleni kwakamuva kwenziwa i-XMM-Newton Space Obsercootopes . Lokhu kwenze ukuthi kwenzeke ukulinganisa ububanzi obungaphandle kodayela lwe-U mon ka-Mon kamakhilomitha acishe abe ngu-82.5 billion amakhilomitha (550 А.) nokuthola i- "hole" encane esikhungweni sayo, isikhala samahhala esinamakhilomitha ayizigidi eziyizinkulungwane ezingama-1,35 (cha Ngaphezu kuka-9 A.), okuhambelana nebanga eliphakeme phakathi kwezinkanyezi zohlelo.
Uhlelo lokujikeleza kohlelo lwenqatshiwe kusuka kulayini wokubheka kusuka emhlabeni ngama-degree angama-75, futhi lapho izinkanyezi zikubanga eliphakeme ukusuka komunye nomunye, zakhiwe zakhiwe ngalolu lwakhiwe ngalo. Ukuqubuka kwezikhathi ezithile kusistimu kuvela ngenxa yenkanyezi ye- "main" star, futhi futhi kungenxa yokuthi, ukuhambisa umjikelezo wayo, kanye njalo ngeminyaka engu-6.5, cishe kufihlwe ngokuphelele yifu eligcwele igesi.
Ngosizo lwedatha ye-Farval, ososayensi baphinde babona izinguquko ekukhanyiseni kwe-U Mon ngezikhathi ezithile zeminyaka engaba ngu-60 - mhlawumbe zibangelwa ukudlula kwesixuku esikhulu segesi nothuli. Ngaphezu kwalokho, ukusebenzisana kwezinkanyezi ezinento onqenqemeni lwangaphakathi lwediski kwakha ukugeleza kwendaba okugeleza kubhekela inkanyezi "encane". Lokhu kubangela ukugqama okwengeziwe ku-XMM-Newton X-ray nge-XMM-Newton Probe: Ngokusho kososayensi, i-Mon isiphenduke ukuguquguquka kokuqala kohlobo lweTaurus RV, olubonwa kulolu banga lwamagagasi.
