Kodi zamoyo wa nyenyezi

Mofanana ndi munthu wina chikhalidwe, nyenyezi simungakhoze kukhala sichinasinthe. Obadwa, kukhala, ndipo potsiriza "kufa". nyenyezi, kusanduka amatenga zaka mabilioni, koma kutsutsana ndi nthawi ya mapangidwe awo. Poyamba asayansi ankaganiza kuti ndondomeko za "kubadwa" wa stardust amafuna zaka mamiliyoni ambiri, koma osati kale litali, munda wa kujambula thambo ku Great Orion Nebula zimapezeka. Mu zaka zochepa chabe, pali zayamba yaing'ono nyenyezi limodzi.

The zithunzi mu 1947 malo awa kagulu ka zinthu nyenyezi ngati wakhala lokhazikika. Ndi 1954, ena a iwo kale elongated, ndipo patapita zaka zisanu, awa zinthu anakomoka mu osiyana. Choncho nthawi yoyamba ndondomeko nyenyezi kubadwa anatenga malo monga kutsogolo a sayansi ya zakuthambo.

Tiyeni tisanthule mwatsatanetsatane mmene kapangidwe ndi zamoyo wa nyenyezi, mmene kuyamba ndi kutha kwa wopandamalire, mwa nzeru za anthu, moyo.

Pachikhalidwe, asayansi amanena kuti nyenyezi anapanga ndi condensation a mitambo ya mapangidwe mafuta ndi fumbi. Mothandizidwa ndi mphamvu yokoka kuchokera chifukwa mpweya kunachita mtambo opaque mpira, wandiweyani mu dongosolo. kukakamiza mkati sangathe moyenera ake mphamvu yokoka compressive. Pang'onopang'ono mpira ali wothinikizidwa kuti auka kutentha nyenyezi subsurface ndi otentha mpweya kuthamanga mkati zibaluni ndi kukwaniritsa mphamvu kunja. Pambuyo pake, psinjika mabasi. Kutalika kwa ndondomeko izi zidalira pa unyinji wa nyenyezi ndi zambiri awiri kwa zaka mazana angapo miliyoni.

Kapangidwe Star kumafuna kutentha kwambiri Interiors zawo, zomwe zimalimbikitsa njira mosadodometsedwa nyukiliya (haidrojeni kuti ndipamene iwo, kwasanduka helium). Zimene zimachitika ndi udindo kwa cheza kwambiri a nyenyezi. Nthawi imene akupereka mwa kundipatsako zilipo a haidrojini anatsimikiza ndi misa zawo. Yomweyi zimatengera pa nthawi cheza cha.

Pamene nkhokwe wa hydrogen ndi zatha, zamoyo wa nyenyezi kubwera ku siteji ya mapangidwe chimphona wofiira. Izi zimachitika motere. Pambuyo discontinuation mphamvu mphamvu yokoka anayamba compress pachimake. Pankhaniyi, nyenyezi kumawonjezera kukula kwambiri. Luminance Komanso kumawonjezera chifukwa ndondomeko ya zochita maphatikizidwe ikupitirira, koma wosanjikiza woonda m'malire a phata la.

Zimenezi limodzi ndi kuwuka mu kutentha kwa helium-wothinikizidwa pachimake ndipo akatembenuka helium mtima kwa mtima mpweya.

Malinga Zoneneratu, dzuwa wathu kungayambitse wofiira chimphona zaka biliyoni atatu. utali wozungulira ake motero zingawonjezere ambiri nthawi, ndi luminosity zingawonjezere ndi maulendo poyerekeza ndi milingo panopa.

Kutalika kwa moyo wa nyenyezi, monga tanenera kale, zimadalira misa. Zinthu misa kuti ndi zosakwana dzuwa, mouma kwambiri "amathera" m'matangadza awo a mafuta nyukiliya, kotero iwo akhoza kuwala makumi a zaka mabilioni.

The zamoyo wa nyenyezi umatha ndi mapangidwe a atumiki woyera. Izi zimachitika kwa iwo, amene misa ili pafupi misa dzuwa, i.e. Kodi musalumphe 1.2 pa izo.

nyenyezi chimphona zambiri mofulumira kuchepetseratu azipeza wa mafuta nyukiliya. Izi limodzi ndi chidwi kuwonda, makamaka chifukwa Yambitsaninso a zipolopolo lakunja. Chifukwa, pali pang'onopang'ono yekha akamazizira gawo chapakati, momwe anachita nyukiliya anasiya kwathunthu. M'kupita kwa nthawi, nyenyezi awa adzaleka kuwala ndi kukhala wosaoneka.

Koma nthawi zina zamoyo wabwinobwino ndiponso dongosolo la nyenyezi akusokoneza. Nthawi zambiri nkhawa zinthu chachikulu chimene ayesa mitundu yonse ya mafuta nyukiliya. Pingakhala lidzasanduke nyutironi, supernovae ndi mabowo wakuda. Asayansi akamaphunzira zambiri za zinthu izi, mafunso yatsopano uka.
