Bootes kuwundana: Bakuman chithunzi

Pakuti mayiko, orienteering, komanso kuphunzira za mlengalenga, nyenyezi zonse akale m'magulu, n'kupanga silhouette zinthu zina kapena anthu lanthano. M'kupita kwa nthawi, kusintha chikhalidwe cha magulu ena, chiwerengero chawo chinawonjezeka. Komabe, ambiri a magulu wakhala anapitiriza dzina lake ndi kasinthidwe ngati iwo anali m'zaka AD chachiwiri, pamene analenga m'ndandanda wake wa Klavdiy Ptolemey. Mwa iwo kuwundana Bootes, ndi Greece wakale, amene anatenga dzina Arktofilaks (mu "wosungira chimbalangondo" Baibulo).

Location mu mlengalenga

Bootes mu kumpoto kwa dziko lapansi Tingaone onse chilimwe. Zimawavuta. Chakwanira kuyang'ana chiyambi cha ku Big wonyika kuwundana Bootes lili kumanzere kwa chogwirira cha ndowa ya. Wakumwamba kujambula ambiri chizindikiro chooneka kwambiri mfundo zake - Arcturus. nyenyezi ndi yowala kwambiri wachinayi, zotsatirazi Sirius, Canopus ndi Alpha Centauri.

lalanje chimphona

Arcturus si nyenyezi yowala mu kuwundana Bootes, ndiye mtsogoleri pa chizindikiro ichi mu Chigawo lonse kumpoto. Mu dziko lathu makamaka noticeable m'chaka. Mpaka pakati chilimwe Arcturus ndi mkulu mokwanira pamwamba m'chizimezime mu mlengalenga kum'mwera. M'dzinja anasamuka kumadzulo, pafupi ndi kaja.

Nyenyezi yowala mu kuwundana Bootes - chimphona lalanje, kupyoza dzuwa nthawi 110 pa luminosity. Chifukwa ripple zonse padziko nyenyezi kuwala uliwonse masiku asanu ndi kusintha pang'ono kwa 0,04 udzakwaniritsidwa. katundu izi amakulolani monga Arcturus ku gulu la nyenyezi variable.

Alendo ochokera Way wina

Mwina, zaka Arcturus ndi pang'ono zaka zoposa biliyoni zisanu ndi ziwiri. Adzaupereka kwa nyenyezi, kupanga otchedwa otaya Arcturus, 52 magetsi kusuntha pafupifupi liwiro chomwecho mbali imodzi. Ena magawo a matupi awa lakumwamba zapangitsa asayansi kuona kuti padangokhala anali mbali ya Way wina, Milky Way odzipereka. Iwo likukhalira kuti akuona kuphunzira Arcturus Padziko Lapansi nthawi yomweyo amaona wina wa nyenyezi wamkulu ndi mlendo kwa kachitidwe kena galactic.

nkhani akale

Arcturus chikugwirizana ndi imodzi mwa nthano kuti afotokoze mmene panali kuwundana Bootes. Imafotokoza kuti Zeus anali lidzasinthidwa nyenyezi Arcadia, mwana wake, kupulumutsa ku imfa. Mabaibulo osiyanasiyana ngwazi anaika pa mlengalenga kapena nyenyezi inayake kuwundana zonse. Mayi ake anali Callisto, mkazi Artemi, kapena mwana wa Mfumu Lycaon. Zeus, pofuna kupulumutsa wake wokondedwa ku chilango cha mkazi anakwiya, Hera, malinga n'kunena kwa Baibulo lina, ku Diana, amene mdzakazi wake anapereka lonjezo la kusakwatira, anatembenuka Callisto ku chimbalangondo. Arcades anakula mlenje kwambiri, ndipo osadziwa nyama mayi ake pafupifupi anamuwombera iye. Kumasulidwa muvi anatenga Zeus. Kenako anaganiza kuchotsa Callisto Arcade ndi kuzunzidwa, kutembenuzira khalidwe mu kuwundana Bootes, ndi mayi wake - mu Big wonyika. Dzina yachiwiri chithunzi Nyenyezi, Arktofilaks, mbadwa ya nthano yemweyo: Arcades mu mlengalenga zonse dogging chimbalangondo atagwira Agalu zazikulu ndi kuteteza ena ndifotokoze mavuto.

Bootes kuwundana ana amakhala osangalatsa monga kugwirizana ake ndi oyandikana nawo dongosolo zakuthambo. Bakuman facilitates kuloweza malo a kanjedza angapo.

dongosolo wapawiri

Bootes kuwundana chiwembu zikuphatikizapo nyenyezi 149 kuonekera kwa apoyera, ndi Arcturus - si chinthu chokha kuchilingalira pakati pawo. komanso Isar (epsilon) zigwire mu kuwala Mufrid (eta) ndi Seginus (Popanga madzi a gamma). Zonse zimene ziri nyenyezi awiri.

Isar kapena Itsar (Arabic "loincloth") - dongosolo chikukhudza chimphona yowala lalanje ndi woyera nyenyezi ndondomeko zikuluzikulu. Mtunda pakati pa iwo ndi 185 zakuthambo mayunitsi, ndi nthawi ya zaka zoposa zikwi.

Mufrid - mnansi wapamtima Arcturus (Bootes kuwundana chithunzi m'munsimu). Chimodzi chigawo dongosolo, mtundu ndi pamwamba kutentha ndi dzuwa lofanana, koma osati zimphona chikasu. Kugonjetsa siteji moyo wawo amakhala ngati mungafike panjira kukhala chimphona wofiira. M'nzake zochepa chidwi magawo ake. Izi ndi nyenyezi yaing'ono wofiira, kunena za zinthu za ndondomeko zikuluzikulu.

Seginus ili pa mapewa a Bootes komanso tichipeza matupi awiri. Zikutanthauza mtundu wa nyenyezi variable Delta chishango ndi luster, kusintha lililonse maola ochepa chifukwa cha pamwamba ripple.

zeta

Kuwundana Bootes ndipo lili pamaso pa nyenyezi patatu. Zikuphatikizapo Zeta. Woyamba awiri zigawo zake (A ndi B) pafupifupi ofanana mu udzakwaniritsidwa. The luminosity uliwonse kuposa chizindikiro ofanana kwa nthawi Sun 38. Pankhaniyi, nyenyezi dongosolo Zeta Bootes - wokongola kuzimiririka malo chinthu ndi mwina Choncho, palibe dzina lina mbiri.

The chigawo chachitatu akadali wa zinsinsi za chilengedwe. Za iye ife tikudziwa kuti chimazungulira awiri anati, monga nthawizonse izo mu kachitidwe ternary, ndipo ali ndi ukulu wa 10,9.

44 Bootes

Mu kuwundana kwa pali wodziwanso kuposa chidwi chinthu cha patatu. Izi 44 Bootes. Close nthunzi mwa dongosolo ndi nyenyezi ziwiri, pafupi wina ndi mnzake kuti kukhudzana pamwamba. 44 boötis B ndi C 44 boötis kutembenuka mzake atatu okha maola mtunda therebetween ndi pang'ono makilomita oposa miliyoni. Malo zedi ngati ali negligible. nyenyezi zonse kupatsana chuma ndipo zimapanga dongosolo wosakhazikika, nthawi zambiri kupoletsa kuphulika wamphamvu.

Dongosolo chigawo ndi ofanana kulemera kwa dzuwa, monga utali wozungulira ake pafupi ndi chizindikiro lolingana kuwala kwathu. Amanena za gulu la G2 V. ndi 44 Bootes ndi bwino. Ndi otsika kwa luminance chigawo ndi kulemera B, ndi m'mimba mwake kwa dzuwa osachepera 40%. Adzaupereka kwa gulu la nyenyezi yaing'ono yachikasu.

Bootes 44 ndi ofanana kwambiri ndi nyenyezi wathu. utali wozungulira ake ndi luminosity zayamba lifanane ndi magawo lolingana kwa dzuwa. Mtunda pamenepa zikuluzikulu za dongosolo ternary zikusintha banja dzuwa, kuyambira kayendedwe kanjira ali mawonekedwe a chowulungika elongated. Pafupifupi kukula kwake - 48,5 zakuthambo mayunitsi.

The makina a Way wathu

Bootes ndi zodabwitsa, ndipo chinthu china aikidwa pa wake "m'gawo." Mu 2006, panali anapeza Way nyenyezi yaing'ono, wotchedwa komanso Bootes. machitidwe oterewa amakhala pakati pa makina wa Milky Way, pokhala naye mu ubale wa yokoka ya kulankhulana Lapansi ndi Moon. Boötes (kuwundana) amene chithunzi sanatero kamodzi telesikopu, anazindikiritsidwa monga mwini wa Way nyenyezi yaing'ono ndi kuwerengetsera kusamala ndi kuwerengetsera. Choncho mdima malo chinthu sikutheka kukonza pa chithunzi chilichonse. Kudziwika nyenyezi otero amagwira ntchito yofunika kwambiri mu akuyenga chiphunzitso cha mapangidwe wa Milky Way ndi chilengedwe.

Bootes, okongola ndi noticeable kuwundana madoko ambiri zinsinsi ndipo adakali mofulumira palibe kuulula zakuthambo awo chidwi. Si onse nyenyezi wake anaphunzira. Nthawi inadutsa mauthenga za zinthu zatsopano wapezeka pafupi Bootes. Tikhoza kuyembekezera kuti kuwundana izi, komanso onse danga kwambiri, adzatipatsa zinthu zambiri kwambiri.
