Altair - inkanyezi, iqhawe tinganekwane ucwaningo luhlobo

Iyatholakala ngokubona okubonakala ngeso lenyama ukuze bagcine ingxenye encane nje kuphela izinkanyezi ukuthi ugcwalise yonke. Nokho, ziyisici okwanele ukuhlola zonke yobukhulu bendawo yonke. Ohlwini izinkanyezi enhle kakhulu endaweni yeshumi nambili kuyinto Altair - inkanyezi, ngokuvamile owawakhiwe izingqondo izazi zezinkanyezi.

indawo

Thola bakhanya ngokwanele nje, hhayi kuphela ngenxa ukukhanya yayo. Star Altair itholakala umlaza Lokhozi, kuyingxenye umxhwele esibhakabhakeni kanye ngokuvamile imakwe kahle. Igama bakhanya libonisa ngokucacile ukuthi ivelaphi. Lisuselwa le "Al-Nasr al-Tair," okuyinto ngesi-Arabhu elisho ukuthi "olundizayo."

Isikhathi esikahle kakhulu ukubona sibalo yasezulwini - kusuka ngoJuni kuze Agasti. Eagle libhekisela nemilaza bhé, futhi ngenxa yalokho kulula ukubona ezindaweni ezimaphakathi naseningizimu yezwe lethu, kanti ezindaweni ezisenyakatho iyatholakala esifundweni. Lesi sibalo wasezulwini amanga eningizimu-ntshonalanga ye-Swan. Eagle ufunde kalula izinkanyezi ezintathu abakha umugqa oqondile cishe ephelele. Kuyinto Altair, futhi Tarazed Alshain. Futhi, izazi zezinkanyezi kuhlanganiswe asterism yabo ugongolo ibhalansi.

legend iqhawe

Altair - inkanyezi ingeyona eyodwa asterism. Inhlanganisela edume kunazo ukukhanya nge iqhaza lakhe iyona Summer Triangle. "Abangane" Altair kuwo - ke Vega (Lyra) kanye Deneb (Cygnus umlaza). Zonke izingxenye elikhanyayo we asterism, kumakwe kahle. base amalungu ezihlukahlukene legends kusukela ezikhathini zasendulo. Ngo enye ibonakala iphethe Altair ongumelusi kanye ngonyaka, ngobusuku Ivana Kupaly, ihlangana Vega yakhe ethandekayo, womeluki.

amapharamitha

Akunzima ukuqagela ukuthi isithombe wasezulwini Lokhozi isihlabani bhá - Altair (-alpha inkanyezi). Kuyinto ukukhanya isigaba Spectral akuyona kude ngaphambi kwelanga ngosayizi. IMisa Altair ngaphezulu izikhathi 1.7 kuka ipharamitha yayo, cishe okufanayo kukhona diameters we ezimbili izindikimba zasezulwini. Ukugqama Alpha Eagle - kakhulu umphumela isondele isihlobo Earth. Altair eLangeni ahlukaniswe mayelana 16.8 light-years. Ngaphezu kwalokho, u-Alpha Eagle licace kakhulu inkanyezi yethu. Likhanya ngendlela efanayo Altair kuyinto izikhathi eziyisishiyagalolunye mkhulu kunezinhliziyo ilanga.

okusheshayo

Altair - inkanyezi, nje kuphela ukukhanya yayo futhi ukubonakala. It libhekene umjikelezo ngokushesha kakhulu emhlabeni-axis awo. Omunye uguquko inkanyezi wenza enkathini eyiminyaka amahora 6 kuya ku-10 (e ezahlukene imithombo yokwaziswa Kuthi ezahlukene). Zazise isivinini ezifana kungenzeka, uma sikhumbula ukuthi ilanga liyadingeka kulesi isikhathi okuningi - zinsuku-25.

Lokhu isivinini kunemiphumela. Altair - Inkanyezi nge ukuma okweqanda. Ukujikeleza Rapid kwaholela isibambo izingongolo ukukhanya endaweni. Ngenxa yalokho, lo ububanzi inkanyezi enkabazwe kuyinto 22% ngaphezu polar. Ekuqaleni, isicaba ukuma Altair kwatholakala ngokuhamba izibalo ze-theory, kodwa ngo-2007, ososayensi babe ubufakazi ukwethembeka zale ezakhiwe.

eyinkimbinkimbi

Inyuvesi Sikhungo Kakhulu Yokufunda Izinkanyezi laseGeorgia high-resolution ochwepheshe, eholwa John Monnier akhethiwe Altair njengento sokutadisha. Kwakufanele enze isifinyezo ebusweni inkanyezi. okuqoshwe kungaba ngowokuqala khombisa seduze kangaka inkanyezi ngaphandle komthala. Nokho, ukuze sithole lezo usayizi izithombe inkanyiso Altair sise elifanayo ukusuka izidingo isibonakude isibuko ukuze amamitha angamakhulu amathathu ububanzi. Ukuze ezingeni lamanje leyo mishini ubuchwepheshe - esikhathini esizayo.

Inkinga esobala akayekile ososayensi. Ukuze usebenze izibonakude ezine, wahlela umbuthano ububanzi 250 m. Ukukhanya ngazifunyana yasetshenziswa, eqoqwe idivayisi, ebizwa ngokuthi "Michigan seso combiner." Ngenxa yalokho, ukukhanya laliqongelelwe ephezulu ukucacisa isithombe.

Imiphumela cwaningo

Star Altair, ogama isithombe senziwa isinqumo esingaphansi amasekhondi amancane ekhoneni, uvele enjalo lokho theory ubikezela - isicaba e izigxobo ndawo. Nokho, ososayensi banesithakazelo kakhulu akuyona. Isithombe yabonisa ukukhanya ezindaweni ezehlukene ebusweni lezinkanyezi. izindawo ngabanye babebhekwa, amnyama futhi ukukhanya. Ngaphezu kwalokho, umehluko waphawula e ukukhaya photosphere we inkanyezi latitude.

Izici waphawula ka Altair angakawamukeli incazelo. Esikhathini kohlaka imiqondo ezamukelwayo izinkanyezi nombala ligijima, ingafaneleki. Idatha etholwe zidinga ucwaningo olwengeziwe enemininingwane ngosizo imishini ezintsha kanye nobuchwepheshe ekhethekile. amasu interferometry Optical ingasetshenziswa ukufunda ebusweni nezinye izinkanyezi eziseduze.

Star Altair izinkanyezi lihlotshaniswa kuhlanganise ne ikhono izibikezelo, nokuthambekela kwezinhliziyo ukucabanga ngaphambi kwenkathi. Mhlawumbe Akukhona ukuthi kumane kuqondane ukuthi lakhanya ukhuthaza ososayensi ukuthuthukisa imishini yabo. Ukwehluleka ukuthola ulwazi olusha mayelana Altair izindlela zocwaningo ubudala, ezinye izenzakalo simbe kohlaka zinkolelo-mbono ezicatshangelwayo yendabuko - konke lokhu kuvusa ukunyakaza umcabango ngokwesayensi futhi ubuchwepheshe etholakalayo ukuba bathuthuke. Namanje-alpha Eagle, kanye wonke umlaza of interest izazi zezinkanyezi eziyizimfundamakhwela. ukusondela Enough nokukhanya kuhlangene ulwazi enganele - lawa izizathu ezinjalo ukulalelisisa Altair. Mhlawumbe esikhathini esiseduze esizayo, ososayensi ziyojabula kithi nalokho okutholakale muva ezihlobene le nkanyezi.
