Supernova - ukufa noma isiqalo esisha?

Izimo zethu zihluke kakhulu abantu abambalwa bangase bazibone lomkhuba ezithakazelisayo njengoba i-supernova. Kodwa lokhu akulona kokuzalwa avamile inkanyezi, ngoba emthaleni wethu bazalwa ngonyaka ukuze izinkanyezi eziyishumi. A supernova - into ezingaba sigujwe kanye kuphela eminyakeni eyikhulu. Ngakho izinkanyezi bhá futhi zizinhle afe.

Ukuze uqonde ukuthi kungani kukhona ukuqhuma supernova, kubalulekile ukuze ubuyele basungulwa izinkanyezi. Isikhala hydrogen ezindizayo okuyinto kancane kancane eqoqwe efwini. Lapho ifu ngokwanele ezinkulu, i-hydrogen ohlangene iqala ukuhlangana isikhungo yawo, futhi izinga lokushisa liyakhula kancane kancane. Ngaphansi kwethonya gravity uya-nucleus inkanyezi, lapho ngenxa lokushisa lenyuka namandla adonsela phansi okwandisa iqala ukuba ibhekane zenuzi Fusion ukuphendula. Kungakanani hydrogen zingathola ngokwayo inkanyezi incike lingakanani esizayo - kusukela yemifino obomvu giant okwesibhakabhaka. Ngokuhamba kwesikhathi, esungulwe izinkanyezi ibhalansi, izingqimba elingaphandle ifaka ingcindezi nengaphakathi ukusebenza, kanye core yandisa ngenxa Fusion amandla.

Iphephandaba iThe Star uhlobo a ophendulayo Fusion futhi, kunoma yisiphi ophendulayo, ngesinye isikhathi uye uphele uphethiloli - hydrogen. Kodwa kithi ukubona ukuthi inkanyezi amabhomu i-supernova, nje idinga isikhathi esincane, ngoba ezinye fuel (helium) kwamiswa lo ophendulayo endaweni e-hydrogen, okuyinto uzoqala ukuba ashise inkanyezi, ukuyivala kube umoya-mpilo bese carbon. Futhi ngakho-ke luyoqhubeka kuze kube yilapho kwakhiwa it is yensimbi, okungadingi ezishisa kakhulu zikhipha izinhlayiyana amandla, futhi kudle-ke ukusabela iArmagedoni e umnyombo inkanyezi. Ngaphansi kwezimo ezinjalo, futhi lesi simo singenzeka ukuqhuma supernova.

I-nucleus iba usinde esibandayo, ngenxa izingqimba engenhla ukuxegiselwa aqala ukuwela phezu kwakhe. Iqala kabusha iArmagedoni ukuphendula zamagama, kodwa ngalesi sikhathi nangesivinini kunalokho ezivamile, abangela Kuqhuma inkanyezi, bahlakaze endaweni ezungeze ndaba yalo. Kuye kobukhulu besabelo inkanyezi, ngemva kungase futhi ahlale "izinkanyezi" amancane. Kakhulu ezidumile yalezi - izimbobo omnyama (into nge high density kakhulu, okuyinto has a esikhulu kakhulu Luhambo amandla , futhi engase ikhiphe ukukhanya). zokwakheka ezinjalo ngemva izinkanyezi ezinkulu kakhulu ukuthi wahluleka ukuzala Fusion ukuze Izakhi ezisindayo kakhulu. izinkanyezi ezincane siyekele inkanyezi neutron noma yensimbi elincane cishe bungakhiphi ukukhanya, kodwa futhi abe high density kwendaba.

Okusha kanye supernovae kuhlobene eduze, ngoba ukufa omunye wabo kungasho ukuzalwa entsha. Le nqubo iyaqhubeka kuze kube nini. Supernova ithwala emkhathini izigidi zamathani ezinto ezibonakalayo, okuyinto waphinda uya efwini, futhi iqala ukwakheka indikimba entsha yasezulwini. Ososayensi baye bame kwelokuthi zonke Izakhi ezisindayo ukuthi zitholakala ezisesimisweni sethu sikanozungezilanga, i-Sun ngesikhathi sokuzalwa kwakhe, "eyebiwe" kusukela inkanyezi yamila kanye. Nature muhle kakhulu, futhi ukufa into eyodwa njalo kusho ukuzalwa into entsha. Esikhathini evulekile ndaba ubola, futhi izinkanyezi kwakhiwa, kwakhiwe ibhalansi omkhulu wendawo yonke.
