1 Stellar Nucleosynthesis ntawm Cov Khoom Cov ntsiab lus no yoghydrogen (H), carbon (C), nitrogen (N), oxygen (O), phosphorous (P), sulfur (S), chlorine (Cl), sodium los ntawm natrium (Na), magnesium (Mg), poov tshuaj los ntawm kalium (K), calcium (Ca), thiab hlau los ntawm ferrum (Fe).
Cov ntsiab lus twg yog tsim nyob rau hauv stellar nucleosynthesis quizlet?
nucleosynthesis? tau tsim los ntawm hydrogen thiab heliumlos ntawm stellar nucleosynthesis qee qhov ntawm cov ntsiab lus tshwj xeeb yog cov uas sib zog dua hlau.
Lub ntsiab lus twg tsis tsim thaum lub sijhawm stellar nucleosynthesis?
Tag nrho cov atoms hauv ntiaj teb tsuas yog hydrogenthiab feem ntau ntawm cov helium yog cov khoom siv rov ua dua --- lawv tsis tau tsim nyob rau hauv lub ntiaj teb. Lawv raug tsim nyob rau hauv lub hnub qub. Kev siv lo lus "tsim" no txawv dua li qhov uas ib txwm txhais los ntawm cov kws tshawb fawb.
Cov ntsiab lus twg yog qhov loj tshaj plaws los ntawm stellar nucleosynthesis?
Lub caij hnyav tshaj plaws uas tuaj yeem ua hauv lub hnub qub yog hlau. Cov ntsiab lus hnyav dua li cov hlau muaj qhov sib xyaw ua ke nrog qhov kub thiab txias thiab qhov xav tau siab tshaj qhov uas tuaj yeem tshwm sim hauv cov tub ntxhais ntawm lub hnub qub loj. Nco tseg: Hauv daim duab uas nyob ib sab, lo lus "hlawv" tiag tiag txhais tau hais tias nuclear fusion!
3 hom nucleosynthesis yog dab tsi?
Synthesis ntawm cov ntsiab lus tshwm sim thiab lawv cov isotopestam sim no nyob rau hauv lub Solar System solids tej zaum yuav muab faib ua peb broad ntu: primordial nucleosynthesis (H, Nws), nquag particle (cosmic ray) kev sib cuam tshuam (Li, Be, B), thiab stellar nucleosynthesis (C thiab hnyav zog.).
