Renyeredzi Dolphin - duku, asi zvinonakidza

Denga of Northern Hemisphere usiku rine kwete chete sezvo zvakawanda uye chinooneka zvinhu, sezvo Orion kana Big Dipper. Kune vazhinji uye hwakaderera zvikuru kwaari kukura enyeredzi. The duku saizi Zvisinei, hazvirevi kuti nhamba yokudenga yakadaro zvishoma zvinonakidza. Renyeredzi Dolphin - mumwe izvi zvinhu. It ane nzvimbo nzvimbo zviduku, asi vamwe zvinhu zvikuru kuziva yakaiswa munharaunda yayo.

muzvinambiri

Renyeredzi Dolphin vana kutanga anooneka munguva kuziva mungano yechiGiriki. Mune rimwe ngano ramwari munyanza, Poseidon akabatidza chido Nereid Amfetrite. Belle ndisingadi kuva unoda zvomumvura hondo uye kutiza kubva kwaari. Nereid yakabatsira kudzorerawo Dolphin. Ndinotenda Poseidon ari kudzokera akamupa nzvimbo kudenga. Kubvira ipapo, renyeredzi of Dolphin uye decorates rising pamusoro pemisoro yazvo.

In Dolphin vavakidzani unobtrusive rakajeka zvakakwana. Renyeredzi riri pedyo asterism Summer Triangle inoumbwa anozivikanwa zvakadai Zvinovheneka sezvo Vega, Deneb uye Altair. C. Dolphin uyewo nenyika vanodhirowa yokudenga Eagle Pegasus Arrows Small bhiza, makava uye Aquarius. Watch zvinogona usiku zvakajeka rinenge nharaunda yose Russia, kunze kuchamhembe kumatunhu. The akanaka nguva - kubva June kusvika September. The maitiro Maumbirwe renyeredzi (nowenyika rengavi) zvichiita nyore kucherechedzwa Chokwadi, kana kusina makore uye zvimwe zvinhu zvinogona kukanganisa maonero.

asterism

Renyeredzi Dolphin mudenga ndokwenguva nzvimbo 189 akaenzana nhambwe. Inoitwa mitumbi matatu, iyo inogona kusiyaniswa chinoabatsira. Zvisinei, vatatu chete wavo anogona kunzi zvakawanda kana zvishoma inopenya nekuti inozivikanwa zvikuru wechina. Vari zvose zvinosanganisirwa huru asterism nhamba iyi yokudenga, rinonzi Coffin Jobho. In yose zviri nyeredzi mana. Ichi chinhu Arufa, Beta, wegamma uye epsilon Dolphin.

First kupenya

Beta renyeredzi riri dzepamusorosoro pfungwa muenzaniso uyu zvokudenga. Kupenya kwaro zvinofungidzirwa panguva 3,63m. Chinovheneka anonzi Rotan uye 97 iri pakukurukurirana. makore kubva zuva. Beta delphini - vakawanda ezvinhu anoumbwa yenhengo maviri. Vose ndezvaJehovha spectral kirasi F5 subgiants. Kure pakati nyeredzi maviri kwazvo diki, saka vaviri haasi kuoneka ose teresikopu. Kujeka luminosity chezvinonhuwira gadziriro iri ka18 kupfuura chete parameter kwezuva. Izvi chete chinhu zvishoma nyeredzi chinooneka zviri 8 nguva mukuru kupfuura nyeredzi yedu.

Zvinhu hurongwa tenderera ane makore 26.7. Maererano zvidzidzo chevanhu vakawanda kupfuura rezuva anenge 2,5 nguva.

Alpha

Pamusoro apa chinovheneka iri zvishoma muduku wakachena Saulotsin. Ndiwo Arifa renyeredzi, ndiyewo munhu binary hurongwa. chikuru chinoumba Its chinhu spectral kirasi B9. Kubva zuva rinenge akaparadzaniswa nevanhu chinhambwe 240 chiedza makore. A maitiro chinhu nevanhu vose nyeredzi ichi mhando - kukurumidza kuruka. pedyo neequator, nokukurumidza rinosvika 160 km / s. Izvi anenge ka70 mukuru kupfuura zuva. To musi, masayendisiti haana kutsunga ndezverudzii Saulotsina chaizvo. Maererano nemamwe mabhuku, iye anotaura nyore chikuru-kutevedzana nyeredzi. Zvakabuda zvimwe Masvomhu kuzobvumira vanokurondedzera sezvo subgiant pakutanga pakati shanduka nzira.

Rokuti wechipiri hurongwa kure kubva pakutanga pa 12 AU. Ivo tenderera ane makore 17. Zviri pachena Saulotsina shamwari nenzira dzakawanda dzakafanana Sirius.

Origin of zita

Kusiyana tsika, mazita Arifa Beta Dolphins havasi Arabic kana echiGiriki. Kokutanga zita akazviratidza katarogu, rakapa pakutanga ari XIX remakore muna Palermo Observatory. Zvishoma Papera, nyanzvi yokuBritain Thomas Vilyam Vebb vakaona kuti mazita uye Saulocin Rotanev kana kuverenga kubva kurudyi kuenda kuruboshwe vanopa zita raNikoraiti Venator. Saka akadana mutevedzeri zvomuchadenga Piazzi Kachatore. Ndiani vaviri, Nicolaus pachake kana ake wepabasa, aiva muvambi mazita akadai achiri chakavanzika.

Pfungwa mubereko

Renyeredzi Dolphin akabata pamusoro munharaunda yayo asi mwero kwete chete chiedza. Pano dziri pasi nebula NGC 6891 uye NGC 6905. The wokutanga wavo ane nokukura 11, uye wechipiri - 12. Vose, kufanana pachake, muenzaniso yokudenga, asi mupfupi.

Mukuwedzera, renyeredzi Dolphin iri yakashongedzwa globular sumbu NGC 6934. Zvayaiva pedyo epsilon payo muenzaniso uyu wokudenga. Asi guru globular sumbu kunoratidzwa nokukura kuti 8,9m. Wechipiri wakafanana nawo chinhu, pamusoro NGC 7006, uyewo kuonekwa chaizvo yakajeka. Kubva Panyika zvinonzi akaparadzaniswa nechiedza-makore anenge zviuru 185.

Asi kwete ndizvo zvose - pane mumwe chinhu, akajeka renyeredzi of Dolphin. Photo iye chete zvakakwana kuwana paIndaneti. Ndicho New Dolphin 2013. Zvivako rakasiyana nemamwe mukuti nguva pfupi asati buri raro, zvazikamwa sechiedza madzerere pamusoro rechi17 zvikuru. Paakanga yakawanikwa ne mudzidzi zvomuchadenga Koichi Itagaki, zvakanga yakajeka zvikuru. Masayendisiti anofungidzira nyeredzi pakarepo akatanga kuvhenekera 25 zviuru nguva kusimba. Zvimwe kwazvinoita kuva chaiwo matsva. Izvi zvinhu vanomiririra binary hurongwa chena pfupi uye chiedza makuru chando. Nokuda kure duku pakati mashoko runoyerera nyeredzi zvakawanda maduku zvinoriumba, uye zviri kupopotedzana. Somugumisiro, pakupedzisira pane kuputika, umo nyeredzi kuramba chakamira. zviedza izvi anogona upenye kakawanda.

A duku renyeredzi of Dolphin, sezvo zviri pachena, ari kunyatsoongororwa zvazvaiita ne vanoongorora nyeredzi. Zvichida zvichava kupa zvakawanda zvinoshamisa.
