Piv txwv li, Hom Ia supernovae yog tsim los ntawm runaway fusion ignited ntawm degenerate dawb dwarf progenitors, thaum lub spectrally zoo sib xws Hom Ib/c yog tsim los ntawm Wolf-Rayet progenitors loj heev los ntawm core vau.
Ua raws li qhov no, dab tsi ua rau Hom 1 supernova?
Ib model li cas a Hom Ia supernova yog tsim los koom nrog rau cov khoom siv rau ib lub ntsej muag dawb los ntawm lub hnub qub hloov zuj zus raws li tus khub binary. Yog hais tias lub accreted loj ua rau Lub ntsej muag dawb dawb kom tshaj qhov txwv Chandrasekhar ntawm 1.44 hnub ci, nws yuav ua rau muaj kev puas tsuaj loj heev los tsim cov supernova.
Tom qab, lo lus nug yog, dab tsi yog ob hom supernova? Muaj ob hom supernova, hu ua (thov txaus) "Type I" thiab ""Type II ".
- Hom I: supernovae TSIS MUAJ hydrogen nqus kab hauv lawv cov spectrum.
- Hom II: supernovae Nrog hydrogen absorption kab hauv lawv cov spectrum.
Xav txog qhov no, supernova tsim li cas?
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 tawg loj heev ntawm ib supernova.
Dab tsi ua rau hom 2 supernova?
A Type II supernova (plural: supernovae los yog supernovas) tshwm sim los ntawm kev tawg sai thiab tawg tawg ntawm lub hnub qub loj. Lub hnub qub fuses ntau dua cov ntsiab lus, pib nrog hydrogen thiab tom qab ntawd helium, nce mus txog ntawm lub rooj zaum kom txog rau thaum ib qho tseem ceeb ntawm cov hlau thiab npib tsib xee raug tsim.

Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Dab tsi cuam tshuam rau cov pioneer hom muaj nyob rau hauv ib puag ncig uas ua tiav thawj zaug?
Cov ecosystems hloov lub sij hawm, tshwj xeeb tshaj yog tom qab muaj kev cuam tshuam, vim qee yam tsiaj tuag thiab cov tsiaj tshiab tsiv mus. Thaum lub sij hawm thawj succession, cov pioneer hom muaj txiav txim seb lwm yam kab mob yuav nyob ntawd
Dab tsi yog txheej txheem ntuj tsim ua rau ib hom pob zeb hloov mus rau lwm hom?
Peb hom pob zeb tseem ceeb yog igneous, metamorphic thiab sedimentary. Peb txheej txheem uas hloov ib lub pob zeb mus rau lwm qhov yog crystallization, metamorphism, thiab yaig thiab sedimentation. Txhua lub pob zeb tuaj yeem hloov mus rau lwm lub pob zeb los ntawm kev dhau los ntawm ib lossis ntau dua ntawm cov txheej txheem no. Qhov no tsim lub voj voog pob zeb
Dab tsi yog supernova thiab dab tsi ua rau nws?
Muaj teeb meem ntau dhau ua rau lub hnub qub tawg, ua rau lub 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, qhov tseem ceeb yog hnyav heev uas nws tsis tuaj yeem tiv taus nws tus kheej gravitationalforce. Cov tub ntxhais hluas tawg, uas ua rau tawg loj heev ntawm supernova
Dab tsi yog qhov txawv ntawm N hom semiconductor thiab P hom semiconductor?
Hauv N-hom semiconductor, cov khoom siv hluav taws xob feem ntau yog cov neeg nqa khoom thiab qhov yog cov neeg nqa khoom tsawg. Hauv P-hom semiconductor, qhov yog feem ntau cov neeg nqa khoom thiab cov khoom siv hluav taws xob yog cov neeg tsawg. Nws muaj qhov loj dua electron concentration thiab tsawg lub qhov concentration. Nws muaj qhov loj dua qhov concentration thiab tsawg dua electron concentration
