Pezani chitsanzo wakumwamba zikhoza, motsogozedwa ndi Great Nyamuliranani, amene kudziwa, monga ulamuliro, palibe amene sayambitsa mavuto. Atali Venatici anayikidwa basi pansi chidebe cha. A mzere kukopedwa kudzera Alefa ndi Popanga madzi a gamma ya Big wonyika mu njira kum'mwera chakum'mawa, kusonyeza mfundo yowala kwambiri kuwundana, nyenyezi, wotchedwa Akor Caroli. Kum'mawa kwa Bootes atali Venatici ili, ngati chikuoneka bwinobwino mu usiku.

Akor Caroli

Alpha atali Venatici - nyenyezi yowala kwambiri kuposa chithunzi zakuthambo. Chotero dzina ndakatulo linapatsidwa kwa iye Charlz Skarboro. Mu 1660, iye akufuna kuti ulitsa thambo kuwundana Akor Caroli, wopangidwa mwa nyenyezi imodzi yokha. zofuna zake chinakwaniritsidwa. "Kuwundana" kwakhalapo mu fomu iyi mpaka cha m'ma XIX. Ndiye dzina Anam'samutsira Alpha atali Venatici. nyenyezi unadzipereka kwa Charles, amene anaphedwa 1649 ndipo ndi atate wa Charles II, pansi pa bwalo umene unali Charlz Skarboro.

Alpha atali Venatici - mmodzi wa kachitidwe wokongola kwambiri bayinare, malinga ndi asayansi ambiri. chigawo Aika ndi buluu koyera nyenyezi yaikulu zinayendera. Ndi zinachitika pa dzina chomwecho kalasi variable nyenyezi. zifukwa zomwe zimayambitsa kusintha kuwala kwa nyenyezi, ndi kasinthasintha ake ndi amphamvu kwambiri maginito. Posachedwapa, kuposa kolowera dzuwa mu nthawi zana. Glitter nyenyezi ndi masiku 5,47 zimasiyanasiyana 2,84 mamita +2,94 m. The maginito kuwala kupatula oscillations izi kulenga chidwi malo kukula ndi heterogeneity mu photosphere anafotokoza danga chinthu.

Mbali yachiwiri ya dongosolo - ndi nyenyezi yaing'ono chikasu, amene ali akuyambira chachikulu.

Yotsatira yowala nyenyezi za chitsanzo zakuthambo wotchedwa Chara. Ndi nyenyezi yaing'ono yachikasu nyenyezi, ndi wa kawalidwe kalasi G. m'njira zambiri nyenyezi ndi dzuwa lofanana ndi. Akatswiri a sayansi amanena kuti ngati mmodzi wa zinthu zosangalatsa kwambiri mu mlengalenga. Mu 2006 Yoyeserera atali Venatici wakhala kuzindikiridwa ngati kuwala kwambiri zingamuthandize kuti kusaka kwa moyo zakuthambo. Pamodzi ndi Alpha CVn amatchedwanso ASTERION, Char akuti "kum'mwera galu."

Mfundo chidwi

Atali Venatici - ndi kuwundana, chomwe chili ndi opondapo kuchuluka kwa formations chidwi dziko kuwonjezera zounikira lapansi. Izi nyenyezi ndi nebulae ndi masango globular. Mmodzi wa iwo - ndi M51. Way ili, lomwe lili ndi dzina la Maelstrom lapansi. Amalekanitsa ku Earth pafupifupi mamiliyoni 23 kuwala zaka. Mbali wa chinthu ndi tichipeza nyenyezi ziwiri. Ambiri a iwo, NGC 5194 ali bwino dongosolo mwauzimu. Chimodzi mwa zida za khamu la nyenyezi linkakhala mu mnzawo NGC 5195. ogwirizira a telesikopu zofufuzafufuza khalani ndi chidwi kudziwa kuti Whirlpool - yekha ngati malo amene inu mukhoza kuwona dongosolo mwauzimu popanda zida akatswiri.

admirers ambiri a zakuthambo ziri zodziwika bwino globular limodzi M3. Pali nyenyezi oposa 500,000. Good ndi chimaonekadi zoyang'anira anapereka kutali kuyatsa m'tawuni.

Sichangozi telesikopu ambiri umalimbana kuwundana atali Venatici. Photo chinthu ku madera ake, ena kuposa zimene zatchulidwa, muli nyenyezi otero wokongola ngati M63 (mpendadzuwa Way), M94 kapena M106. Komanso onse si odziwika kwa zakuthambo za nyenyezi chitsanzo wakumwamba. Zikuoneka kuti atali Venatici ndakonza kwambiri zodabwitsa kwa ife.
