Hom Ia supernovae yog cov kev tshawb fawb muaj txiaj ntsig ntawm cov qauv ntawm lub ntiaj teb, vim lawv txhua tus muaj tib lub luminosity. Los ntawm kev ntsuas qhov ci ntsa iab ntawm cov khoom no, ib qho kuj ntsuas qhov nthuav dav ntawm lub ntiaj teb thiab qhov kev hloov pauv ntawm lub sijhawm.
Ib yam li ntawd, hom 1 supernovae siv rau quizlet yog dab tsi?
Lwm txoj hauv kev ntsuas qhov deb yuav tsum yog siv rau ntau galaxies nyob deb. Ib ntawm txoj kev zoo tshaj plaws: Hom Ia supernovae , uas tau siv ntsuas qhov deb mus txog 3,000 Mpc. Hom Ia Supernovae tab tom tawg cov dwarfs dawb. Tej zaum lawv yuav tshwm sim nyob rau hauv ze binary hnub qub nrog huab hwm coj hloov ntawm ib lub hnub qub mus rau ib tug dwarf dawb.
Tsis tas li ntawd, qhov txawv ntawm Hom 1 thiab Hom 2 supernovae yog dab tsi? A type I supernova tshwm sim nyob rau hauv kaw binary systems qhov twg ob nruab nrab hnub qub orbit nyob ib ncig ntawm ib tug heev ze. Thaum twg ib ntawm cov hnub qub tso tawm nws cov hydrogen nws yuav nkag mus rau theem liab loj heev thiab tom qab ntawd tawg mus rau hauv ib lub dwarf dawb. A hom II supernova tshwm sim nyob rau hauv cov hnub qub loj ntawm ib ncig ntawm 10 hnub ci pawg.
Ua kom pom qhov no, hom 1a supernovae siv rau dab tsi?
Kev siv ntawm Hom Ia supernovae Txhawm rau ntsuas qhov kev ncua deb yog pioneered los ntawm kev koom tes ntawm Chilean thiab US astronomers, Calán / Tololo Supernova Kev soj ntsuam.
Dab tsi yog hom supernovae?
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.

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
