Qhov tseeb, supernovae tuaj hauv txawv flavors, pib los ntawm ntau hom ntawm hnub qub, xaus nrog ntau hom ntawm explosions, thiab ua ntau hom ntawm seem. Nyob ntawd yog ob lub ntsiab hom supernovae , cov Hom Kuv thiab Hom II.
Ib yam 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.
Tsis tas li ntawd, hom 1 supernova tsim li cas? A hom Ia supernova (nyeem " typ ib -a") yog a hom ntawm supernova uas tshwm sim nyob rau hauv binary systems (ob lub hnub qub orbiting ib lwm) uas ib ntawm lub hnub qub yog ib tug dawb dwarf. Lwm lub hnub qub tuaj yeem ua txhua yam los ntawm lub hnub qub loj mus rau ib qho me me dua dawb.
Ib yam li ntawd, koj tuaj yeem nug, Dab tsi yog qhov txawv ntawm Novas?
Main sub- chav kawm ntawm novae yog classical novae, recurrent novae (RNe), thiab dwarf novae. Lawv tag nrho suav tias yog lub hnub qub cataclysmic sib txawv. Classical nova eruptions yog feem ntau typ nov.
Puas yog cov seem ntawm hom II supernovae?
Tus nto moo tshaj plaws Type II supernova , SN 1987A, kuj yog ib qho txawv heev. Tsis zoo li SNIa qhov twg tsis muaj dab tsi nyob tom qab tawg, SNII nyiam tsim supernova seem ntawm ejected stellar cov ntaub ntawv uas nyob ib ncig ntawm lub hnub qub neutron los yog pulsar (yog hais tias cov tub ntxhais loj yog tsawg tshaj li ntawm 3 hnub ci masses), los yog lub qhov dub.

tsib Ntxiv mus, muaj pes tsawg hom monomers muaj nyob rau hauv cov hmoov txhuv nplej siab? Nyob ntawd tsuas yog 1. Ib yam li ntawd, qhov sib txawv ntawm nucleic acids yog dab tsi? Ob yam tseem ceeb ntawm nucleic acids yog deoxyribonucleic acid (DNA ) thiab ribonucleic acid (RNA).
Muaj pes tsawg hom teeb muaj?
peb Tib neeg kuj nug tias, lub teeb sib txawv yog dab tsi? Lub Electromagnetic Spectrum sab nraud pom tau muab faib ua ntau qhov chaw uas tseem muaj cov npe tshwj xeeb: xov tooj cua tsis, microwaves, infrared, ultraviolet, x-rays thiab gamma rays.
Muaj pes tsawg hom kev khaws cia lub zog muaj?
Hom lub zog tuaj yeem muab faib ua ob pawg dav - lub zog kinetic (lub zog ntawm cov khoom txav) thiab lub zog muaj peev xwm (lub zog uas khaws cia). Cov no yog ob hom kev siv zog
Muaj pes tsawg hom kev scaling muaj?
