Hauv kwv yees li 5 billion xyoo, lub hnub yuav pib txheej txheem helium-hlwb, tig mus rau hauv ib lub hnub qub liab . Thaum nws nthuav, nws txheej txheej yuav noj Mercury thiab Venus, thiab ncav cuag lub ntiaj teb. Thaum twg hnub qub morph ua liab giants , lawv hloov qhov chaw nyob ntawm lawv qhov system.
Cia li xav txog qhov no, yuav ua li cas ib tug liab giant ua ib tug dawb dwarf?
Thaum lub hnub qub tsawg dua li ntawm 8 lub hnub ci huab cua khiav tawm ntawm hydrogen hauv nws cov tub ntxhais, feem ntau helium tub ntxhais tawg thiab kub. Thaum nws tau kub txaus fusion tshwm sim pib nyob rau hauv txheej ntawm hydrogen nyob ib ncig ntawm lub hauv paus. Qhov no ua rau cov txheej txheej ntawm lub hnub qub nthuav dav mus rau hauv ib qho loj loj . Lub hnub qub yog tam sim no a dwarf dawb.
Ib yam li ntawd, muaj dab tsi tshwm sim hauv lub hnub qub liab loj? Liab Giant . Thaum hydrogen roj ntawm qhov chaw ntawm a hnub qub yog sab sab, cov tshuaj tiv thaiv nuclear yuav pib tawm mus rau hauv nws cov huab cua thiab hlawv cov hydrogen uas nyob hauv lub plhaub nyob ib puag ncig cov tub ntxhais. Yog li ntawd, sab nraud ntawm lub hnub qub pib nthuav thiab txias, tig ntau redder.
Tom qab ntawd, piv txwv li lub hnub qub liab loj yog dab tsi?
Piv txwv ntawm paub zoo hnub qub Hauv RG theem yog Aldebaran (Alpha Tauri) thiab Mira (Omicron Ceti). Ntau qhov Main Sequence hnub qub evolve sai dua thiab nthuav ntxiv mus ua Liab Super Giants (RSG). Betelgeuse (Alpha Orionis) yog qhov paub zoo piv txwv ntawm RSG.
Puas yog Jupiter yog lub hnub qub ua tsis tiav?
Jupiter npe a ua tsis tiav lub hnub qub vim hais tias nws yog tsim los ntawm tib lub ntsiab (hydrogen thiab helium) raws li yog lub hnub, tab sis nws tsis loj txaus kom muaj lub sab hauv siab thiab kub tsim nyog los ua hydrogen fuse rau helium, lub zog qhov chaw uas powers lub hnub thiab feem ntau lwm yam. hnub qub.

Yuav ua li cas rau ib tug nruab nrab lub hnub qub thaum nws tuag?
Qhov kawg ntawm cov pa roj hydrogen nyob rau hauv lub plhaub sab nraud yog cua tshuab mus ua ib lub nplhaib nyob ib ncig ntawm lub hauv paus. Thaum kawg ntawm helium atoms nyob rau hauv cov tub ntxhais yog fused rau hauv carbon atoms, lub hnub qub nruab nrab pib tuag. Lub ntiajteb txawj nqus ua rau qhov kawg ntawm lub hnub qub teeb meem mus rau sab hauv thiab compact. Qhov no yog qhov dawb dwarf theem
Yuav ua li cas koj pom qhov nruab nrab thiab nruab nrab ntawm daim duab peb sab?
Txhawm rau nrhiav qhov chaw nruab nrab ntawm daim duab peb sab, nws yog qhov yooj yim tshaj plaws los kos tag nrho peb qhov nruab nrab thiab nrhiav lawv qhov kev sib tshuam. Txhawm rau kos qhov nruab nrab ntawm daim duab peb sab, ua ntej nrhiav qhov nruab nrab ntawm ib sab ntawm daim duab peb sab. Kos ib kab ntu uas txuas qhov taw tes no mus rau qhov rov qab vertex
Dab tsi yog qhov txawv ntawm ib tug liab giant thiab ib tug supergiant?
Yog li, tsis zoo li cov neeg loj heev, liab supergiants tsuas yog ci, cov hnub qub liab. Nws yog li ntawd tshwm sim hais tias lawv yuav nyob rau hauv tib lub evolutionary lub xeev, tab sis kuj muaj peev xwm hais tias lawv tau tsiv mus nyob rau. Piv txwv li, feem ntau cov hnub qub loj yuav tshwm sim li liab supergiants thaum helium yog fused rau hauv cov pa roj carbon hauv cov tub ntxhais
Koj pom qhov nruab nrab thiab nruab nrab hauv tableau li cas?
Kev sib txuas lus cov ntaub ntawv nrog Tableau los ntawm Ben Jones Qhov nruab nrab (lossis nruab nrab) yog txiav txim siab los ntawm kev suav tag nrho cov txiaj ntsig hauv cov ntaub ntawv teev thiab faib los ntawm tus lej ntawm qhov tseem ceeb. Qhov nruab nrab yog tus nqi nruab nrab hauv cov ntaub ntawv teev nyob rau hauv uas qhov tseem ceeb tau muab tso rau hauv kev txiav txim ntawm qhov loj
Koj ua li cas sib npaug redox cov tshuaj tiv thaiv hauv acidic thiab nruab nrab nruab nrab?
Acid Conditions Solution. Kauj Ruam 1: Sib cais ib nrab cov lus teb. Kauj Ruam 2: Ntsuas cov ntsiab lus uas tsis yog O thiab H. Kauj Ruam 3: Ntxiv H2O kom sib npaug ntawm cov pa. Kauj Ruam 4: Sib npaug hydrogen los ntawm kev ntxiv protons (H +). Kauj Ruam 5: Ntsuas tus nqi ntawm txhua qhov sib npaug nrog electrons. Kauj Ruam 6: Ntsuas cov tshuaj tiv thaiv kom cov electrons sib npaug
