Liab supergiants yog cov hnub qub nrog cov luminosity supergiant chav kawm ntawm spectral hom K lossis M. Lawv yog cov hnub qub loj tshaj plaws hauv ntiaj teb hais txog qhov ntim, txawm tias lawv tsis yog qhov loj tshaj plaws lossis luminous.
red supergiant science txhais txhais li cas?
Liab supergiants yog cov hnub qub supergiant ntawm spectral hom K-M thiab chav kawm luminosity ntawm I. Hnub qub nrog ntau tshaj li 10 hnub ci, tom qab hlawv lawv cov hydrogen ua liab supergiants thaum lawv helium - hlawv theem. … Cov hnub qub no muaj qhov kub thiab txias heev (3500-4500 K), thiab radii loj.
tus liab supergiant ua dab tsi?
Txhua tus supergiants liab yuav tso cov helium hauv lawv cov cores hauv ib lossis ob lab xyoo thiab tom qab ntawd pib hlawv carbon. Qhov no txuas ntxiv nrog kev sib xyaw ntawm cov ntsiab lus hnyav dua kom txog rau thaum cov tub ntxhais hlau tsim, uas tom qab ntawd inevitably vau los tsim lub supernova.
piv txwv liab supergiant yog dab tsi?
Ib qho piv txwv ntawm lub hnub qub supergiant liab yog Antares119 Tauri, Betelgeuse, Mu Cephei, Stephenson 2-18 thiab VV Cephei yog lwm cov piv txwv nto moo ntawm liab supergiants. Feem ntau cov hnub qub supergiant liab tawg ua supernovae, tab sis qee qhov ci ntsa iab dhau los ua Hma-Rayet hnub qub ua ntej tawg.
lub hnub qub liab supergiant txhais li cas?
Filters Ib lub hnub qub loj loj thiab luminosity uas muaj qhov kub thiab txias ntawm qhov sib txawv ntawm 3,000 txog 4,000 kelvin (4, 940 ° txog 5, 740 ° F), muab cov xim liab los yog txiv kab ntxwv xim. npe. Lub hnub qub liab loj heev uas muaj qhov tsawg kawg nkaus ntawm 15 hnub ci.
