Muaj teeb meem ntau dhau ua rau lub hnub qub tawg , ua rau a supernova . Raws li lub hnub qub khiav tawm ntawm cov roj nuclear, qee qhov ntawm nws cov huab cua ntws mus rau hauv nws cov tub ntxhais. Thaum kawg, lub hauv paus tseem hnyav heev uas nws tsis tuaj yeem tiv taus nws tus kheej lub zog gravitational. Cov tub ntxhais hluas tawg, uas ua rau loj heev tawg ntawm a supernova.
Ib yam li ntawd, nws tau nug, yuav ua li cas tshwm sim hauv qhov tawg ntawm supernova?
Qhov no tawg tshwm sim vim qhov chaw, los yog lub hauv paus, ntawm lub hnub qub tawg nyob rau hauv tsawg tshaj li ib ob. Cov txheej txheej sab nrauv ntawm cov hnub qub raug tshuab tawm hauv tawg , tawm hauv kev cog lus tseem ceeb ntawm lub hnub qub tom qab lub supernova . Cov kev poob siab thiab cov khoom uas ya tawm ntawm lub supernova tuaj yeem ua rau tsim cov hnub qub tshiab.
Ib tug kuj nug, puas yog supernova tawg lossis implosion? Lub teeb ci ntsa iab yog qhov tawg ntawm lub hnub qub uas tau mus txog qhov kawg ntawm nws lub neej, txwv tsis pub paub raws li ib tug supernova . Supernovae tuaj yeem luv luv outshine tag nrho galaxies thiab radiate ntau zog tshaj peb lub hnub yuav nyob rau hauv tag nrho nws lub neej. Lawv kuj yog qhov tseem ceeb ntawm cov ntsiab lus hnyav hauv lub qab ntuj khwb.
Tom qab ntawd, ib tug kuj yuav nug, nws yuav siv sij hawm ntev npaum li cas rau lub supernova tawg?
Ob peb lab lub xyoo rau lub hnub qub tuag, tsawg dua li ib feem peb ntawm ib lub thib ob rau nws cov tub ntxhais kom tawg, ob peb teev rau lub shockwave mus txog saum npoo ntawm lub hnub qub, ob peb lub hlis kom ci, thiab tom qab ntawd tsuas yog ob peb xyoos kom ploj mus. nyob deb.
Lub supernova tawg loj npaum li cas?
Cov hnub qub no xaus lawv cov kev hloov pauv hauv cosmic loj tawg lub npe hu ua supernovae . Thaum twg supernovae tawg , lawv jettison teeb meem rau hauv qhov chaw ntawm qee qhov 9,000 txog 25,000 mais (15,000 txog 40,000 kilometers) ib ob.
