Neutron hnub qub tig heev ceev ceev tom qab lawv tsim vim yog kev txuag ntawm lub zog ntawm angular; nyob rau hauv analogy kiv cov dej khov skaters rub hauv lawv txhais tes, qhov kev sib hloov qeeb ntawm qhov qub lub hnub qub core nrawm nrawm thaum nws shrinks.
Ib yam li ntawd, nws tau nug, vim li cas koj xav tias cov hnub qub neutron yuav tig nrawm?
Peb cia siab tias cov hnub qub neutron yuav tig nrawm vim lawv khaws cia angular momentum. Ntau lub pulsars muaj lub sijhawm ntawd yog maj mam nce raws li cov spinning neutron hnub qub poob zog. Qhov kev tshwm sim lub qab ntug kos tus ciam teb nyob rau hauv uas qhov ntom yog roughly tib yam li cov atomic nucleus.
Tsis tas li ntawd, vim li cas cov hnub qub neutron tig nrawm nrawm? Neutron hnub qub yog tsim los ntawm lub cev qhuav dej ntawm loj hnub qub . Txij li tag nrho hnub qub tig , lub hauv paus ntsiab lus ntawm kev txuag ntawm angular momentum kwv yees tias yog ib qho loj heev hnub qub collapses nws yuav tsum tig nrawm dua kom txuag angular momentum.
Tom qab ntawd, ib tug kuj yuav nug, vim li cas lub millisecond pulsars tig ceev heev?
Feem ntau cov pulsar tig ob peb zaug ib ob, tab sis qee qhov kiv pua pua zaus sai dua . Cov no yog li ntawd - hu ua millisecond pulsars nplawm ib ncig yog li ntawd sai sai vim hais tias lawv xav tias yuav tau tshem tawm huab hwm coj - thiab angular momentum - los ntawm cov hnub qub khub ntawm qee qhov chaw hauv lawv cov keeb kwm.
Lub hnub qub neutron kav ntev npaum li cas?
Yog koj nug ntev npaum li cas a neutron hnub qub tuaj yeem kuaj pom tau raws li lub pulsar, cov lus teb yog tias nyob rau hauv cov catalog tsis ntev los no ntawm pulsars (pulsars yog rotating. neutron hnub qub ), cov laus tshaj 10, 000, 000, 000 xyoo (txawm hais tias feem coob ntawm cov pulsars yog nyob nruab nrab ntawm 100, 000 thiab 300, 000, 000 xyoo.

Yam khoom twg feem ntau txiav txim siab seb lub hnub qub loj lossis lub hnub qub supergiant yuav tsim?
Pawg (1) feem ntau txiav txim siab seb lub hnub qub loj lossis lub hnub qub supergiant yuav tsim. Cov hnub qub tsim nyob rau hauv cov cheeb tsam ntawm qhov ntom ntom hauv thaj tsam interstellar. Cov cheeb tsam no yog hu ua molecular huab thiab muaj feem ntau ntawm hydrogen. Helium, nrog rau lwm cov ntsiab lus, kuj pom nyob rau hauv cheeb tsam no
Peb yuav txiav txim siab li cas hnub nyoog ntawm cov hnub qub?
Qhov tseem ceeb, astronomers txiav txim siab hnub nyoog ntawm hnub qub los ntawm kev soj ntsuam lawv cov spectrum, luminosity thiab motionthrough space. Lawv siv cov ntaub ntawv no kom tau txais lub hnub qub profile, thiab tom qab ntawd lawv muab lub hnub qub piv rau cov qauv uas qhia tias hnub qub yuav tsum zoo li cas ntawm ntau lub ntsiab lus ntawm lawv cov kev hloov pauv
Vim li cas peb thiaj cia siab tias cov kab mob Gram tsis zoo yuav stain liab liab thaum lub sij hawm Gram staining txheej txheem?
Thaum cov kab mob gram zoo stain violet vim muaj cov txheej txheem peptidoglycan tuab nyob rau hauv cov phab ntsa ntawm lawv cov cell, cov kab mob gram tsis zoo stain liab, vim yog cov txheej peptidoglycan thinner hauv lawv cov phab ntsa ntawm tes (peptidoglycan txheej tuab dua tso cai rau cov kab mob gram zoo stains violet. tuav lub stain, tab sis ib txheej nyias
Puas yog lub hnub qub neutron yog lub hnub qub tuag?
Lub hnub qub neutron yog lub hauv paus tawg ntawm lub hnub qub loj uas ua ntej kev sib tsoo muaj tag nrho ntawm 10 thiab 29 hnub ci loj. Neutron hnub qub yog cov hnub qub me tshaj plaws thiab ntom ntom, tsis suav nrog lub qhov dub, qhov tseeb ntawm qhov dawb, quark hnub qub thiab cov hnub qub coj txawv txawv
Vim li cas lub hnub qub loj loj hloov pauv txawv ntawm lub hnub qub qis?
Vim li cas lub hnub qub loj loj hloov pauv txawv dua li lub hnub qub qis? A) Nws tuaj yeem hlawv roj ntau dua vim tias nws cov tub ntxhais tuaj yeem kub dua. Nws muaj lub ntiajteb txawj nqus qis dua yog li nws tsis tuaj yeem rub ntau cov roj los ntawm qhov chaw
