Yellow Star: imizekelo, umahluko phakathi kweenkwenkwezi umbala

Nawuphi star - qanda, bhlowu okanye obomvu - yinto ibhola ebomvu-eshushu yerhasi. Ukuhlelwa Modern leenkwenkwezi kusekelwe eziliqela iparameters. Ezi ziquka iqondo lobushushu, ubungakanani kunye ukukhanya. Umbala iinkwenkwezi azibonayo ngobusuku ecacileyo, kuxhomekeke ikakhulu kuqala parameter. Izibane zishushu blue okanye blue, abanda - ebomvu. iinkwenkwezi Yellow, imizekelo apho zikhankanywe ngezantsi, babe ngabantu abakwizihlalo eliphakathi kwi isikali lobushushu. Phakathi kwezi ukukhanya engena nelanga.

umahluko

, Umzimba, ndinobushushu amaqondo ezahlukeneyo kukhutshwe ukukhanya okukhanya ukungalingani. Le parameter uzimisele kwaye kuxhomekeke iliso umbala yabantu. I mfutshane ombala, umzimba ashushu, kwaye kufutshane umbala mhlophe, nemisonto emsi. Oku kuyinyaniso ukuba iinkwenkwezi.

Isibane ebomvu abanda. iqondo lobushushu kufika kumgomo kuphela amawaka amathathu. inkwenkwezi etyheli njengelanga lethu, sele kushushu. photosphere waso lashushu 6000º. izibane White red-ashushu nokuba ngakumbi - ukusuka degrees-10 ukuya ku-20 amawaka. Ke ekugqibeleni, iinkwenkwezi eziluhlaza ke ishushu. iqondo lobushushu ufikelela phakathi kwe-30 ne-100 lamawaka degrees.

iimpawu ngokubanzi

Yellow iinkwenkwezi, amagama amaninzi ezaziwa kakuhle kunye nabantu kude isuswe ngeenkwenkwezi, oosonzululwazi bafumanisa kukuninzi. Ahluke ngobukhulu, ubunzima, likhanya, kunye nezinye iimpawu. Common wamaziko anjalo - ukuba iqondo lobushushu eli.

ukukhanya Yellow iza kufumana ngexesha zazivelela. Nangona kunjalo, uninzi inkwenkwezi leyo ukwakweli ngolandelelwano engundoqo പ്രൊസീജിയര് indlela-Russell umzobo. Oku kubizwa ngokuba yi-UDema etyheli, ezibandakanya ilanga.

Eyona nkwenkwezi yenkqubo

Seven ezinjalo adalwa ebizwa ngenxa ubukhulu encinane kakhulu. Sun ububanzi imvula 1.39 x 10 ⁹ m, ubunzima - 1,99 x 10 ³⁰ kg. Zombini i parameters axhome kakhulu kunalawo uphawu Umhlaba kodwa emajukujukwini, aba into ngaphandle zesiqhelo. Kukho nezinye iinkwenkwezi ezityheli, njengoko kuboniswe ngezantsi, ukude ngaphambi kwelanga ubukhulu.

Iqondo lobushushu ukukhanya kwethu ifikelela 6 tysyach Kelvin. Sun libhekisela G2V yeklasi ecacicleyo. Enyanisweni, oko ke likhupha ukukhanya emhlophe phantse nyulu,, ngenxa yobume ojikeleze umhlaba xa ifunxwe yi elifutshane-wave yinxalenye zazo. Ngenxa yoko ithinti etyheli.

Iimpawu yingqakumbana emthubi

adalwa ubungakanani ezincinane ebalasele elide umxhelo. I-avareji Ixabiso le parameter - kwiminyaka billion 10. Ilanga ngoku isendaweni phakathi umjikelo wobomi, oko kukuthi, ukuba ziphume ulandelelwano engundoqo kwaye ajike abe isigebenga elibomvu, lona luhlala malunga 5 billion kwiminyaka.

Star, mthubi, kwaye emalunga uhlobo 'ezincinanana "ineenkalo efana nelanga. umthombo wamandla lwemizimba ezinjalo - Yindibanisela helium hydrogen. Inyathelo ngendaleko elilandelayo zihamba emva kokuqala kernel neliphela hydrogen yokutsha helium.

Ngaphandle ilanga ukuya yingqakumbana emthubi libhekisa Alpha Centauri A, Alpha Corona ezimibalabala, Bootes Mu, uTau Ceti kunye nezinye Makube.

subgiants Yellow

Stars ezifana ilanga, emva kokugqiba hydrogen, baqale ukutshintsha. Kanye ngaphakathi kwinucleus a izibane helium Shining kwandiswa ibe elikhulu ebomvu. Nangona kunjalo, eli nyathelo lungenzeki ngoko nangoko. Okokuqala, baqale aqhumisele oomaleko engaphandle. Le nkwenkwezi uye engundoqo-sequence, kodwa noko eyandisiweyo - kuba kwiqonga subgiant. Ubunzima kwezibane ezinjalo kudla iyahluka ukusuka ku-1 ukuya kwisi-5 izihlwele elanga.

sigaba subgiant Yellow ingaqhuba kunye umdla ngakumbi ubungakanani nkwenkwezi. Noko ke, kubo, ngeli thuba ngaphantsi kubi. Le subgiant idumileyo namhlanje - oko Procyon (Alpha Canis Minor).

lwepaki real

iinkwenkwezi Yellow, abamagama banikwa ngentla, eziqhelekileyo ngayo iifayile iphela. izinto ngenye indlela ne hypergiants. Ezi zinde yokwenene, eyayiqwalaselwe ngeyona ndlela imasikizi, eqaqambileyo enkulu, yaye kwangaxeshanye ukuba iminyaka imfutshane ubomi. Inkoliso hypergiants ezaziwayo kukho izinto eziqaqambileyo oluhlaza, kodwa kukho phakathi kwabo ezimhlophe, iinkwenkwezi ezityheli, kwaye obomvu.

Phakathi kwezi imizimba isithuba kunqabile ziquka, umzekelo, Rho Cassiopeia. Oku hypergiants mthubi, likhanya 550 lamawaka amaxesha outstripping ilanga. Ukusuka iplanethi yethu luthe lwancothulwa kwi 12,000 iminyaka elula. Ngobusuku ecacileyo ungabona ngeliso lenyama (ibonakale kokukhanya - 4,52m).

supergiants

Hypergiants - ityala ezizodwa supergiants. Le yokugqibela lukwaquka iinkwenkwezi ezityheli. Bona, ngokutsho izazi, liqonga yenguqu nasekusungulweni ukukhanya okuluhlaza ukuya supergiant ebomvu. Noko ke, kwinqanaba yinkwenkwezi supergiant etyheli ingaphila ixesha elide ngokwaneleyo. Ngokuqhelekileyo, kweli nqanaba musa kufa ukukhanya zazivelela. Kuzo zonke izifundo indawo engaphandle oko kwabhalwa ezimbini kuphela supernovae eyenziwe supergiants ezityheli.

Ezi izikhanyiso ziquka Canopus (Alpha Carinae) Rastaban (Beta Dragon), Beta Aquarius kunye nezinye izinto.

Njengoko kubonakala, inkwenkwezi nganye, emthubi njengelanga, inemisebenzi ethile. Noko ke, bonke unento ofana - umbala olubangelwa ukususela ubushushu le photosphere kumaqondo ezithile. Ngaphandle kwezi, ukuya izikhanyiso zibala Epsilon Shield kunye Beta Corvi (iingxilimbela eqaqambileyo), i-Southern Triangle Delta and Beta Camelopardalis (supergiants), Capella kunye Vindemiatrix (iingxilimbela) kunye neminye imibutho emininzi yesiqalo. Kufuneka kuqatshelwe ukuba umbala ekubhekiswe kuyo ukuhlelwa yento ayisoloko idibana kunye ezibonakalayo. Oku kwenzeka ngenxa yokuba umbala lokwenyaniso ukukhanya ngokushiywa ngenxa igesi kunye eluthulini, yaye emva acandacanda emoyeni. Ukuze ukwazi umbala akhona usebenzisa umatshini spectrograph: ukuba inika ulwazi oluchanekileyo kakhulu ngaphezu iliso yabantu. Enkosi kuwo, izazinzulu uyakwazi ukwahlula iinkwenkwezi eziluhlaza, mthubi kunye ebomvu, kude kuthi apha ezikude.
