Supernova - tuag los yog ib tug tshiab pib?

Kuj muaj ob peb cov neeg muaj peev xwm soj ntsuam cov nthuav phenomenon raws li ib tug supernova. Tab sis qhov no yog tsis ib tug dog dig me nyuam yug ntawm ib lub hnub qub, vim hais tias nyob rau hauv peb galaxy yug los txhua xyoo rau kaum hnub qub. Ib tug supernova - ib tug tshwm sim uas yuav muaj cai ib zaug xwb nyob rau hauv ib puas xyoo. Yog li ntawd kaj thiab zoo nkauj hnub qub tuag.

Yuav kom to taub yog vim li cas muaj ib tug supernova tawg, nws yog tsim nyog los mus rov qab mus rau lub heev yug me nyuam ntawm cov hnub qub. Lub hydrogen ya qhov chaw uas yog maj sau nyob rau hauv cov huab. Thaum cov huab sufficiently loj, compacted hydrogen pib sib sau ua ke nyob rau hauv qhov chaw ntawd, thiab qhov kub thiab txias yog maj zog. Nyob rau hauv tus ntawm lub ntiajteb txawj nqus yog yuav mus rau qhov nucleus ntawm lub hnub qub, qhov twg vim lub zog kub thiab ua kom lub ntiajteb txawj nqus pib mus yauv mus nuclear fusion cov tshuaj tiv thaiv. Yuav ua li cas npaum li cas hydrogen yuav kos rau nws tus kheej lub hnub qub nyob rau nws yav tom ntej loj - los ntawm lub liab ntsias mus giant xiav. Thaum lub sij hawm, tsim cov hnub qub ua hauj lwm tshuav nyiaj li cas, tus txheej khaubncaws sab nraud povtseg ntawm muab siab rau cov tub ntxhais, thiab cov tub ntxhais expands vim fusion zog.

Lub hnub qub yog ib hom ntawm ib tug fusion reactor thiab, nyob rau hauv tej reactor, tej tsam nws tau khiav tawm ntawm roj - hydrogen. Tab sis rau peb saib yuav ua li cas lub hnub qub pob tawg lawm nyob rau hauv ib tug supernova, cia li xav tau ib tug me ntsis lub sij hawm, vim hais tias cov lwm yam roj (Helium) twb tsim nyob rau hauv lub reactor nyob rau hauv qhov chaw ntawm hydrogen, uas yuav pib mus hlawv lub hnub qub, xa nws mus rau hauv cov pa thiab ces carbon. Thiab yog li ntawd nws yuav mus txuas txog rau thaum nws yog tsim ntawm hlau, uas tsis emit zog, thiab haus nws nrog thermonuclear tshua nyob hauv lub hnub qub tub ntxhais. Nyob rau hauv xws tej yam kev mob, thiab muaj peev xwm tshwm sim supernova tawg.

Lub keeb yuav hnyav zog thiab txias tshaj, raws li ib tug tshwm sim ntawm cov sib zog sab sauv khaubncaws sab nraud povtseg pib los poob rau nws. Restarts thermonuclear cov tshuaj tiv thaiv synthesis, tab sis lub sij hawm no sai dua li ib txwm, ua rau cov hnub qub cia li tawg, tawg mus rau hauv lub surrounding chaw cov teeb meem. Nyob rau hauv lub qhov ntau ntawm cov hnub qub, tom qab nws kuj nyob twj ywm me me "hnub qub". Qhov tseem nto moo ntawm cov - dub qhov (ib yam khoom nrog tsis tshua muaj neeg siab ceev, uas muaj ib tug heev loj attraction quab yuam , thiab yuav emit teeb). Tej formations yog tom qab ib tug heev loj hnub qub uas ua tsis tau tejyam yuav tsim ib tug fusion heev hnyav ntsiab. Me hnub qub tawm hauv qab ib tug neutron lub hnub qub los yog ib tug me me hlau uas yuav luag tsis emit teeb, tab sis kuj muaj ib tug kev kub ceev ntawm qhov teeb meem.

Tshiab thiab supernovae yog ze ze, vim hais tias txoj kev tuag ntawm ib tug ntawm lawv muaj peev xwm txhais tau hais tias cov me nyuam yug ntawm ib tug tshiab ib. Qhov no txheej txheem ntxiv indefinitely. Supernova yog mus rau hauv qhov chaw lab ntawm tons ntawm cov ntaub ntawv uas, uas yog ib zaug dua yuav mus rau qhov huab, thiab pib tsim ntawm ib tug tshiab xilethi-aus lub cev. Zaum cam hais tias tag nrho cov heavy hais tias yog nyob rau hauv peb hnub ci system, lub hnub thaum lub sij hawm nws yug los, "raug nyiag lawm" los ntawm lub pob tawg lawm hnub qub ib zaug. Xwm yog amazing, thiab kev tuag ib yam dab tsi ib txwm txhais tau tias cov me nyuam yug ntawm ib yam dab tsi tshiab. Nyob rau hauv lub qhib qhov chaw muaj teeb meem decomposes, thiab nyob rau hauv lub hnub qub tsim, tsim ib tug zoo nqi koj tshuav ntawm lub ntug.
