Thaj chaw hluav taws xob yog txheej tuab ntawm cov ionized heev, cov roj nkev hnyav heev uas nyob rau hauv qhov kev sib tsoo tas li los ntawm gamma rays los ntawm cov tub ntxhais Nws yog kwv yees li 75% hydrogen thiab 24% helium. Vim tias feem ntau ntawm cov atoms ntawm no tsis muaj electrons, lawv tsis tuaj yeem nqus photons rau convection rau saum npoo.
tshav ntuj tawg yog dab tsi?
Tsuas yog sab nraum Sab Hauv Tsev ntawm lub hnub ntawm qhov deb kwv yees li 0.25 txog 0.7 hnub ci hluav taws xobdag Radiative Zone. Cov cheeb tsam no radiates lub zog los ntawm cov txheej txheem ntawm photon emission thiab ntes los ntawm hydrogen thiab helium ions.
Zoo hluav taws xob tsim los ntawm dab tsi?
Hnub ci tshav ntuj yog qhov ntu ntawm hnub ci sab hauv nruab nrab ntawm cov tub ntxhais hauv nruab nrab thiab thaj chaw sab nrauv Nyob rau hauv cheeb tsam radiative, lub zog tsim los ntawm nuclear fusion nyob rau hauv cov tub ntxhais txav tawm sab nraud raws li hluav taws xob electromagnetic. Hauv lwm lo lus, lub zog yog xa los ntawm photons.
Dab tsi yog qhov chaw convection ntawm lub hnub?
Thaj chaw convection yog txheej txheej sab hnub tuaj sab hauv. Nws txuas ntxiv los ntawm qhov tob txog 200, 000 km txoj cai mus rau qhov pom qhov chaw. Ntawm lub hauv paus ntawm thaj chaw convection qhov kub yog txog 2,000,000 ° C.
Lub hom phiaj ntawm hluav taws xob yog dab tsi?
Thaj chaw hluav taws xob yog qhov qhov chaw thauj hluav taws xob tshwm sim thaj chaw no tuaj yeem ua tus yam ntxwv raws li qhov chaw uas peb, cov duab hluav taws xob, thaws ib puag ncig kom yooj yim lub peev xwm thauj mus rau sab nrauv ntawm lub hnub. Qhov kub ntawm thaj tsam hluav taws xob yog li ntawm 2 txog 7 lab degrees Celsius.
