Tsuas yog sab nraum Sab Hauv Tsev ntawm lub hnub nyob ntawm qhov deb kwv yees li 0.25 txog 0.7 hnub ci hluav taws xob nyob ntawm Radiative Zone. Thaj chaw no radiates lub zog los ntawm cov txheej txheem ntawm photon emission thiab ntes los ntawm hydrogen thiab helium ions.
Vim li cas qhov hluav taws xob ntawm lub hnub opaque?
Cov kab hluav taws xob yog txheej tuab ntawm cov ionized heev, cov pa roj ntau heevuas nyob rau hauv qhov kev foob pob tsis tu ncua los ntawm gamma rays los ntawm cov tub ntxhais. Nws yog hais txog 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.
Lub hnub ci ntsa iab txhais li cas?
Hnub ci tshav ntuj yog ntu ntawm hnub ci sab hauv nruab nrab ntawm cov tub ntxhais sab hauv thiab sab nrauv convective zone 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.
Lub hom phiaj ntawm thaj chaw 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.
Puas yog thaj chaw radiative yog txheej ntawm lub hnub?
Cov txheej sab hauv yog the Core, Radiative Zone thiab Convection Zone. Cov txheej txheej sab nrauv yog Photosphere, Chromosphere, Thaj Chaw Hloov Pauv thiab Corona. IRIS yuav tsom mus rau nws qhov kev tshawb nrhiav ntawm Chromosphere thiab Transition Region.
