Ib lub hnub qub qhov kaj , los yog luminosity , nyob ntawm lub hnub qub nto kub thiab loj. Yog tias ob lub hnub qub muaj tib qhov chaw kub , lub hnub qub loj dua yuav luminous. Cov Hertzsprung-Russell ( H-R ) daim duab hauv qab no yog ib daim phiaj uas qhia txog tus txheeb ze kub thiab luminosities ntawm ntau lub hnub qub.

Hauv qhov no, kev sib raug zoo ntawm cov xim kub thiab qhov ci hauv HR daim duab yog dab tsi?

Hnub qub nrog a siab kub yog xiav thiab ci, thaum hnub qub nrog a qis kub liab thiab dim.

Qhov thib ob, qhov kev sib raug zoo ntawm luminosity thiab kub ntawm lub ntsiab yog dab tsi? Cov tshuaj tiv thaiv nuclear yog rhiab heev rau kub yog li ntawd txawm ib tug me ntsis nce nyob rau hauv kub ua rau cov tshuaj tiv thaiv nuclear tshwm sim ntawm tus nqi ntau dua. Qhov no txhais tau tias lub hnub qub luminosity nce ntau yog tias cov kub yog siab dua.

Yog li ntawd, dab tsi yog qhov kev sib raug zoo ntawm stellar xim kub thiab luminosity?

Raws li qhov loj ntawm lub hnub qub nce, luminosity nce. Yog tias koj xav txog nws, lub hnub qub loj dua muaj thaj tsam ntau dua. Qhov chaw saum npoo av nce ntxiv tso cai rau ntau lub teeb thiab lub zog tawm. Kub kuj cuam tshuam rau lub hnub qub luminosity.

Luminosity Yog Ua Los Ntawm

Daim duab HR hais txog lub hnub qub qhov kub li cas?

Kev piav qhia: Daim duab H-R ( Hertzsprung-Russell daim duab ) kuj hu ua xim-magnitude daim duab . Nws qhia txog kev sib raug zoo ntawm hnub qub kub (xim) rau lub lub hnub qub absolute magnitude (luminosity). Qhov loj kawg nkaus yog lub hnub qub Pom meej qhov loj ntawm qhov deb ntawm 10 Parsec ntawm lub ntiaj teb.
