Cov interstellar nruab nrab yog intimately intertwined nrog cov hnub qub. Cov hnub qub yog tsim los ntawm lub cev qhuav dej ntawm cov pa thiab plua plav hauv cov huab molecular. Cov roj uas tseem tshuav nyob ib ncig ntawm cov hnub qub uas tsim los loj heev ua rau thaj tsam HII. Cov interstellar nruab nrab yog li ntawd plays ib tseem ceeb lub luag haujlwm hauv tshuaj evolution ntawm galaxy.

Ib yam li ntawd, peb txhais li cas los ntawm interstellar nruab nrab?

Nyob rau hauv astronomy, lub interstellar nruab nrab (ISM) yog qhov teeb meem thiab hluav taws xob uas muaj nyob hauv qhov chaw nruab nrab ntawm lub hnub qub hauv lub galaxy. Qhov teeb meem no suav nrog cov pa roj hauv ionic, atomic, thiab molecular daim ntawv, nrog rau plua plav thiab cosmic rays. Nws puv interstellar qhov chaw thiab sib tov zoo rau hauv qhov chaw intergalactic ib puag ncig.

Tsis tas li ntawd, lub sij hawm twg ntawm lub hnub qub nruab nrab tuaj yeem tsim cov hnub qub? Cov cheeb tsam ntom ntom no feem ntau yog qhov chaw ntawm kev tsim protostar thiab vau ntawm huab cua loj rau daim ntawv rau hauv hnub qub pawg. Interstellar Plua plav : Interstellar plua plav yog tsim nyob rau hauv lub hnab ntawv nyob ib ncig ntawm liab supergiant hnub qub . Stellar cua thiab lub planetary nebula theem tshem tawm qhov no hmoov av rau hauv interstellar nruab nrab.

Yog li ntawd, qhov nruab nrab interstellar cuam tshuam nrog cov hnub qub li cas?

Thaum ib qho kev poob siab dhau los ntawm huab cua molecular, hnub qub tau yug. Shock yoj taug kev los ntawm ISM, lub interstellar nruab nrab , ua tau ua rau qee qhov chaw ntawm huab cua molecular mus rau hauv qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom hnub qub . Thaum cov huab molecular vau los ntawm kev poob siab, lawv tawg.

Vim li cas lub hnub qub nruab nrab thiaj li kub?

Interstellar Medium : Kub . Qhov hnyav tshaj plaws, thiab yog li kub tshaj plaws, ejection roj rau hauv lub interstellar nruab nrab yog los ntawm supernova tawg. Ib qho supernova remnant (SNR) yog cov qauv uas tshwm sim los ntawm qhov tawg loj heev ntawm lub hnub qub hauv lub supernova.
