<prompt> Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu: Passage: Alpha Gruis ane nyeredzi kupatsanura pamusoro B6 V, kunyange zvazvo mamwe manyuko kupa kupatsanura pamusoro B7 IV. Kurongwa kwokutanga kunoratidza kuti iri inyeredzi yorudzi rweB iri mumutsetse mukuru wenyeredzi dziri kugadzira simba kupfurikidza nokupindana kwenyukireya yehydrogen mukati. Zvisinei, kirasi yechiedza cheIV yaizoratidza kuti iri inyeredzi duku; zvichireva kuti mvura yehydrogen iri mukati mayo iri kupera uye nyeredzi yatanga nzira yokushanduka-shanduka ichibva munhevedzano huru. Iyo haina shamwari dzinozivikanwa. Iyo yakayerwa angular dhayamita yenyeredzi iyi, mushure mekugadzirisa kutonhora kwemativi, i1.02 0.07 mas. Panhambwe yakayerwa parallax yemakore-chiedza 101 31 parsecs kubva kuPasi, izvi zvinopa ukuru hwepanyama hwe3,4 nguva yezuva rezuva. Iri kutenderera nokukurumidza, ine kumhanyisa kutenderera kunofungidzirwa kweanenge 215 km s inopa muganho wezasi wechiyero chekutenderera kweazimuthal pamwe neiyo equator. Nyeredzi iyi ine huremu hunenge hunopetwa kana hweZuva uye iri kupenya zvakapetwa ka520 kupenya kweZuva. Tembiricha yeAlpha Gruis yekunze ndeye 13,920 K, ichimupa ruvara rwebhuruu-chena runozivikanwa nenyeredzi dzeB-type. Huwandu hwezvinhu zvisiri hydrogen nehelium, izvo vanoongorora nyeredzi vanodana kuti metallicity, hunenge 74 hwehuwandu hweZuva. Zvichienderana nezera rakarongwa uye kufamba, inogona kunge iri nhengo yeboka rinotenderera reAB Doradus iro rinotenderera pamwe chete muchadenga. Boka iri rine makore anenge mamiriyoni 70 emakore, ayo anoenderana nezera ra α Gruis remakore 100 emakore achibvumira kukanganisa. Zvikamu zvemhepo zvinomhanya zveyeredzi iyi muGalactic coordinate system zviri U, V, W 7.0 1.1, 25.6 0.7, 15.5 1.4 kms. Mubvunzo: Makore echiedza mangani?  <response>: 10 1 - Zvinhu
