Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Chimwe chinhu chinoratidza kuti supernova iyi yakavapo inonzi close binary star system. Gadziriro yebhinari yemadzitateguru ine nyeredzi dzorudungwe rukuru, dzine uremu hukuru kupfuura hwechipiri. Zvaari mukuru mumasumbu, wokutanga ndiye wokutanga pavaviri ava kuti ashandukire kubazi guru risingapindirani, uko envelope yenyeredzi inowedzera zvikuru. Kana nyeredzi mbiri idzi dziine envelope imwe chete, gadziriro yacho inogona kurasikirwa nehuremu hwakawanda, zvichideredza angular momentum, orbital radius uye nguva. Pashure pokunge nyeredzi yokutanga yaparara kuva nyeredzi duku chena, nyeredzi yechipiri gare gare inoshanduka kuva hofori tsvuku uye nhambo yacho yakagadzirirwa kuwanda kwezvizhinji kunzvimbo yokutanga. Munguva iyi yokupedzisira yokugoverana envelope, nyeredzi mbiri idzi dzinopindana zvikuru sezvo simba rokukurumidzira rinorasika. Nzira inotenderera nayo inogona kuva nenguva pfupi semaawa mashomanana. Kana kuwanda kwacho kukapfuurira kwenguva refu yakakwana, chikomana chichena pakupedzisira chingagona kusvika kumuganhu weChandrasekhar.  Mubvunzo: Muganhu wei nokuswedera pedyo kwenyeredzi duku chena kana kuwedzera kwacho kuchipfuurira kwenguva yakati?
