Nyenyezi lalikulu mu Milky Way

Mwa onse ananena matupi akumwamba ndi kovuta kudziwa ndi nyenyezi lalikulu mu mlalang'amba wathu. Zimenezi zimaphatikizapo zotalikirana danga ndi kuvuta kuzipenya ndi kusanthula wotsatira wa deta. Pakali pano, asayansi anatha kuona ndi kulembetsa pafupifupi 50 biliyoni nyenyezi. Kukweza luso limachititsa kufufuza ngodya kutali kwa chilengedwe, ndi kupeza zinthu zatsopano za zinthu.

Bwino ndi kufufuza supergiants danga

astrophysics zamakono kufufuza malo nthawi zonse anakumana ndi mafunso ambiri. Chifukwa cha ichi ndi chachikulu kukula kwa kuziona, biliyoni khumi kuwala zaka. Nthawi zina, kuonera nyenyezi, zovuta amanena mtunda izo. Choncho musanayambe kugunda msewu pofufuza za tanthauzo la zimene ndi nyenyezi lalikulu Way wathu, m'pofunika kumvetsa mlingo wa Kuvuta kwa kuwunika zinthu danga.

Poyambirira, pamaso pa chiyambi cha zaka mazana makumi awiri, iwo ankakhulupirira kuti Way wathu yekha. Looneka nyenyezi zina monga mamembala a nebulae lapansi. Koma Edvin Habbl anakanthanso onongani kwa dziko ankaonetsetsa. Anaonetsa kuti lalikulu zosiyanasiyana za nyenyezi, ndi wathu si lalikulu.

Space ndi amazipanga yaikulu

Distance kwa nyenyezi yapafupi ndi yaikulu. Zafika mamiliyoni mazanamazana zaka. Pakuti astrophysicists ndi mabvuto kudziwa zimene nyenyezi lalikulu Way wathu. Choncho, pa nyenyezi ina ndi matrilioni a nyenyezi, pa mtunda wa kuwala zaka mamilioni zana limodzi ndi, ndi ngakhale kovuta kunena. phunziro anatsegula nthambi yatsopano. nyenyezi anapeza akuyerekezedwa ndi kutumikira kwambiri wapadera ndi zazikulu.

Supergiant mu kuwundana Scutum

Dzina la nyenyezi zazikulukulu mu mlalang'amba wathu - UY Chikopa, ndi supergiant wofiira. Izi nyenyezi variable, kukula kwa amene zimasiyanasiyana 1700 ndi 2000 Sun diameters.

ubongo wathu sangathe kugonjera chikuperekedwa ofanana. Choncho, timvetsetse mmene chachikulu nyenyezi lalikulu mlalang'ambawu, kulinganizidwa ndi mfundo zomveka kwa ife. Yerekezerani, ubongo wathu dzuwa adzachita. kukula kwa nyenyezi kwambiri kotero kuti ngati aikidwa pa malo a Dzuwa lathu, malire a supergiant ndi pa kanjira Saturn a.

Ndipo dziko lathuli ndi Mars adzakhala mkati mwa nyenyezi. Mtunda "ching'ona chimene" wa danga za 9600 kuwala zaka.

Nyenyezi lalikulu mlalang'ambawu, Mlalang'ambawo - UY Chikopa - zitha salembedwa ngati "mfumu." Pali zifukwa zoonekeratu. Mmodzi wa iwo - ichi ndi chachikulu mtunda dziko ndi fumbi dziko, complicating deta yolondola. Vuto lina kugwirizana mwachindunji ndi katundu thupi supergiants. Ndi awiri a nthawi 1700 lalikulu kuposa thupi wathu wakumwamba, nyenyezi lalikulu Way wathu monga chachikulu ngati 7-10 basi kuchoka kwa iye. Iwo likukhalira kuti supergiant kachulukidwe miliyoni nthawi ang'onoang'ono kuposa mumpweya. kachulukidwe ake angafanane ndi m'mlengalenga pamalo okwera za zana makilomita pamwamba pa nyanja. Choncho, mabvuto zokwanira kudziwa kwenikweni pamene nyenyezi kumalire kutha ndipo akuyamba ake "mphepo".

Pa nthawi, nyenyezi lalikulu Way athu amakhala kumapeto kwa mkombero moyo wawo. Iwo anawonjezera (zikufana ndi mmene zidzachitikire ndi dzuwa wathu kumapeto kwa kusanduka) ndi chiyambi cha yogwira kuyatsa helium ndi ena zinthu zina zolemera kwambiri kuposa wa hydrogen. Patapita zaka zochepa miliyoni nyenyezi lalikulu mlalang'ambawu - UY Chikopa - isanduke supergiant chikasu. Ndi m'tsogolo - mu wowala variable buluu, ndiponso mwina nyenyezi Wolf - Rayet.

Pamodzi ndi "mfumu" - UY supergiant chishango - Tingaone khumi nyenyezi ndi miyeso ofanana. Zikuphatikizapo VY Canis Majoris, Cepheus A, NML Cygni, WOH G64 vv ndi ena.

Amadziwika kuti nyenyezi zonse lalikulu kutha ndi yovuta. nyenyezi awa akhoza kukhalapo kwa zaka mamiliyoni ambiri, ndi zaka zikwi zingapo, mathero ake mkombero moyo monga supernova kapena dzenje wakuda.

Nyenyezi lalikulu mlalang'ambawu: kufufuza akupitiriza

, Kodi tiyenera kuganiza kuti nthawi kulimvetsa bwino nkotheka supergiants magawo adzakhala osiyana ndi kusintha poyamba ananena kuona kwambiri pa zaka makumi awiri zapitazi. Ndipo ndithu mwina, supergiant wina, ndi kulemera wamkulu kapena kukula adzatsegulidwa mu zaka kubwera. A latsopano kutsegula Kukumana kwa asayansi kubwerezanso chiphunzitso kale analandira ndi matanthauzo.
