Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Te haerenga: I tētahi wā i te wā kei te heke mai, ka pau i a IK Pegasi A te pūkaha hauwai i tōna pūoko, ā, ka tīmata ki te whanake atu i te raupapa matua ki te hanga i tētahi whetū whero. Ka taea e te taupoki o te whetu whero te tipu ki te rahi nui, ka toro atu ki te kotahi rau nga wa o tona radius o mua (he nui ake ranei). Ka whakawhānui ana a IK Pegasi A ki te wāhi e rere ana tōna āputa o waho ki te porohita Roche o tōna hoa, ka hangaia he kōpae tāpiri hau huri noa i te kākano mā. Ko tēnei hau, ko te nuinga o te hauwai me te helium, ka piki ki runga i te mata o te hoa. Mā tēnei whakawhitinga papatipu i waenganui i ngā whetū ka whakaiti hoki i to rātau ara tahi. I runga i te mata o te whetū mā, ka kōpeke, ka wera hoki te hau i tāpirihia. I etahi wa ka tae te hau kua kohia ki nga tikanga e tika ana kia puta te whakakotahitanga o te hauwai, ka whakaputa i tetahi urupare rere ke ka peia tetahi waahanga o te hau mai i te mata. Ka hua tēnei ki tētahi (whakare) pūtukitanga nova - he whetū rerekē whakamataku - ā, ka tere ake te ranu o te whetū mā ki te maha o ngā rahi mō te wā o ētahi rā, marama rānei. Ko tētahi tauira o taua pūnaha whetū ko RS Ophiuchi, he pūnaha takirua kei roto i tētahi whetū whero me tētahi hoa whetū mā. Kua mura a RS Ophiuchi ki roto i te nova (hou) i te iti rawa e ono nga wa, i ia wa e piki ana te taumaha nui o te hauwai e hiahiatia ana hei whakaputa i te pahūtanga rere. Ka taea pea e IK Pegasi B te whai i tetahi tauira rite. Hei kohikohi papatipu, heoi, ko tetahi waahanga noa iho o te hau kua whakaemihia ka taea te peia, na ma ia huringa ka piki haere te papatipu ma. Na, ahakoa ka mahi ano ia hei nova, ka taea e IK Pegasus B te haere tonu ki te kohikohi i te kopare tipu. Ko tetahi tauira rereke e ahei ai te kaitiaki ma ki te kohikohi i te papatipu me te kore e pakaru hei nova e kiia ana ko te puna X-ray supersoft tata-rua (CBSS). I roto i tēnei āhuatanga, ko te tere whakawhiti i te papatipu ki te papatipu papatipu ma e tata ana kia taea ai te pupuri i te tahunga whakakotahitanga i runga i te mata i te taenga mai o...  Patai: Kia pehea te tere o te Pegasus A?
