Constellation Dolphin - encinane, kodwa umdla

Isibhakabhaka ebusuku yoMntla saseNtla iqulethe kungekuphela nje izinto olubanzi nebonakalayo, njengoko Orion okanye Big Dipper. Kukho ezininzi ngaphantsi kakhulu kuye namakroza ubukhulu. Ubukhulu elincinane kakhulu, kunjalo, akuthethi ukuba loo manani izikhakhamela kangako umdla. Constellation Dolphin - enye yezi zinto. Singene nje encinci, kodwa ezinye izinto kunokuba ukwazi ezibekwe nommandla wayo.

legend

abantwana Constellation Dolphin kuqala livela ngexesha noqheleneyo kwiintsomi zamaGrike. Kwenye kumabali uthixo iilwandle, Poseidon babase uthando Nereid Amfetrite. Belle akazange afune ukuba uyamthanda womkhosi zaselwandle abaleke emke kuyo. Nereid iye yanceda ukubuyela ihlengesi. Nombulelo Poseidon ngokubuya wamnika indawo ezulwini. Ukususela ngoko, lekroza of the Dolphin kwaye lihombise sithe zinzi phezu kweentloko zabo.

nokubekwa

In avulekile Dolphin abamelwane eziqaqambileyo ngokwaneleyo. Constellation ibekwe kufuphi unxantathu asterism Summer ezenziwa ezifana izikhanyiso eyaziwa ngokuba Vega, Deneb kunye Altair. C. Dolphin nayo ngomda imizobo zesibhakabhaka Eagle Pegasus Arrows ihashe amancinci, Iimpungutye zinemingxuma Aquarius. Wati kungaba ebusuku ecacileyo phantse yonke indawo eRashiya, ngaphandle imimandla wasentla. Ixesha elifanelekileyo - ukususela ngoJuni ukuya kuSeptemba. Imilo uphawu lekroza (embhoxo yephepha) yenzela lula ukuluqonda, Kakade, ukuba akukho emafini kunye nezinye izinto oko akuphazamisi ukubonakala.

asterism

Constellation Dolphin esibhakabhakeni ligubungela ummandla izidanga square 189. It iqulathe kwamaziko amathathu, leyo azakubalulwa ngeliso lenyama. Noko ke, ezintathu kuphela kubo ukuze kuthiwe ngaphezulu okanye eqaqambileyo ngaphantsi kuba ebonakala ubukhulu yesine. Bonke ziqukiwe asterism engundoqo eli nani wasezulwini, ebizwa Coffin kaYobhi. Xa iyonke ke iinkwenkwezi ezine. Le i Alpha, beta, wesigrike kunye epsilon Dolphin.

ukukhanya First

umlaza Beta yeyona ngongoma iphambili yale ndlela yasezulwini. ukukhanya kwayo liqikelelwa kwi-3,63m. Isikhanyiso kuthiwa Rotan kunye 97 elise kunxibelelwano. iminyaka ukusuka elangeni. delphini Beta - inkqubo ezininzi yabhalwa inamacandelo amabini. Bobabini bangamalungu ukuya subgiants iklasi F5 ecacicleyo. Umgama phakathi iinkwenkwezi ezimbini incinane kakhulu, ngoko kwisibini leyo alibonakali kuzo zonke kweteleskopu. Icandelo likhanya Kukhulu le nkqubo izihlandlo ezili-18 ngaphezu parameter efanayo kwelanga. Olu phawu efanayo inkwenkwezi ngaphantsi okubonakalaliswayo amaxesha 8 obungaphezu inkwenkwezi yethu.

Elements lweenkqubo phendula ngesithuba seminyaka 26.7. Ngokutsho izifundo kunobukhulu ngaphezulu solar malunga 2.5 amaxesha.

alpha

Echazwe ngentla isikhanyiso na enasilela kancinane Saulotsin ukukhanya. Nguwo lo umlaza alpha, naye yinkqubo kabini. inxalenye yalo esentloko kukuba libe B9 yeklasi ecacicleyo. Ukusuka ilanga kokuba ezahlulwe sisithuba kumgama 240 iminyaka elula. Eyona isici kuzo zonke iinkwenkwezi olu hlobo - spin ngokukhawuleza. kufuphi neikhweyitha, isantya ufikelela 160 km / s. Oku 70 amaxesha ngaphezu koko kwelanga. Ukuza kuthi ga ngoku, izazinzulu ziye ayixhomekekanga ncam uhlobo Saulotsina. Ngokutsho kweminye imithombo, ubhekisela a iinkwenkwezi eziphambili-ulandelelwano olulula. Iziphumo kwezinye ubalo ukuvumela ukuba bakuchaza nje subgiant ekuqaleni endleleni yendaleko.

Ilungu lesibini umatshini okude ukusuka yokuqala ngo-12 AU. Bona benza ngesithuba seminyaka 17. Kuyabonakala ukuba, Saulotsina iqabane ngeendlela ezininzi efanayo Sirius.

Imvelaphi yegama

Ngokwahlukileyo isiko, amagama alpha beta Dolphins azikho amagama Arabhu okanye isiGrike. Ngokuba lixesha lokuqala igama ivele ikhathalogu, ekhutshwe ekuqaleni kwenkulungwane XIX e Palermo Observatory. Thile kamva, lo ngeenkwenkwezi yaseBritani Thomas Vilyam Vebb wafumanisa ukuba amagama kunye Saulocin Rotanev xa sifunda ukusuka ekunene ukuya ekhohlo unika igama lamaNikolawo Venator. Ngoko wabiza umncedisi ngeenkwenkwezi Piazzi Kachatore. Ngubani na kwaba bobabini, uNicolaus yena okanye umphathi wakhe, waba yimbangi isibizo olunjalo ingaziwa.

Points of interest

Constellation Dolphin ibamba endaweni yayo kunokuba nemadlana kuphela ukukhanya. Apha indawo nebula NGC 6891 kunye NGC 6905. Inkqubo yokuqala kubo wukulu-11, kwaye eyesibini - 12 Bobabini, njengaye, indlela wasezulwini, kunokuba yayimfutshane ngesithomo.

Ukongeza, lekroza Dolphin i zinokuhonjiswa globular cluster NGC 6934. Ifunyanwa kufutshane epsilon kuyo le ndlela wasezulwini. Kunokuba Iqela elikhulu globular luphawulwa ubukhulu ukuba 8,9m. Eyesibini ezifana umzekelo, ka-NGC 7006, kwakhona ingqalelo ukuba kakhulu eliqaqambileyo. Ukusuka Umhlaba kokuba ezahlulwe sisithuba malunga 185 amawaka ukukhanya-iminyaka.

Kodwa loo nto konke - kukho enye into, elihombise lekroza of the Dolphin. Photo naye nje ngokwaneleyo ukufumana kwi Internet. Le New Dolphin 2013. sibonelelo ekhethekileyo yokuba ngaphambi umqala, oko kwaziwa ngokuba nasekuzeni 17 yobukhulu. Xa yafunyanwa ngama ngeenkwenkwezi engahlawulwayo Wayeke Itagaki, kwakuba lubeka phi. Izazinzulu ziqikelela inkwenkwezi aqala kwakhanya 25 amawaka amaxesha eyomeleleyo. Mhlawumbi ngaba kunxulumene classic entsha. Ezi zinto zimele inkqubo kokubini lwe nenomlanga ezimhlophe kunye ukukhanya okukhulu kubanda. Ngenxa umgama ezincinane phakathi izinto aqukuqela iinkwenkwezi ngakumbi amacandelo amancinane, kwaye itshiswa. Ngenxa yoko, kungekudala emva koko kukho kuqhuma, apho iinkwenkwezi bunjalo. Ezi zibane ukuze kukhazimla ngokuphindaphindiweyo.

A constellation encinane Dolphin, njengoko kubonakala, ngokusondeleyo esweni izazi. Mhlawumbi kuya kunika izimanga ezininzi.
