Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Chinhu chinopenya zvikurusa chegadziriro yacho, Sigma Scorpii Aa, ibhinari ine mitsetse miviri, izvo zvinoreva kuti vaviri vacho havana kugadziriswa vachishandisa teresikopu. Panzvimbo pezvo, kutenderera kwavo kunosarudzwa nokuchinja kwechiono chavo chakabatanidzwa chinokonzerwa nokuchinja kwaDoppler. Izvi zvinoratidza kuti vaviri ava vanopedza kufamba kwakatenderedza nyika kamwe chete pamazuva 33.01 uye vane eccentricity ye0.32. Chinhu chikuru chechiviri chechiedza, Sigma Scorpii Aa1, inyeredzi hombe yakashanduka-shanduka ine nyeredzi yeB1 III. Rine uwandu hunopetwa ka18 hweZuva uye nharaunda yaro yakapetwa ka12 yeZuva. Nyeredzi iyi iri kupenya zvakapetwa ka29000 kupenya kweZuva kubva kumhete yayo yekunze pane tembiricha inoshanda ye26150 K. Iyi nyeredzi inoshanduka yerudzi rweBeta Cephei, ichiita kuti hukuru hunoonekwa huchinje pakati pe +2.86 ne +2.94 ine nguva dzakawanda dze0.2468429, 0.239671, uye 8.2 mazuva. Munguva yega yega yekuputika, tembiricha yenyeredzi inosiyana ne4000±2000 K. Imwe nhengo yepakati vaviri, Sigma Scorpii Aa2, inyeredzi huru yekuteedzana ine classification yeB1 V. Kutenderera iyi binary pakuparadzaniswa kwehafu ye arcsecond, kana angangoita 120 Astronomical units (AU), kanokwana kana kureba kweZuva neNeptune, ndiko kukura kwe +5.2 Sigma Scorpii Ab, iyo ine nguva yekutenderera yemakore anopfuura zana. Kunyange kure zvikuru pamasekonzi 20 e arc, kana kuti kupfuura 4500 AU, kune Sigma Scorpii B ine ukuru hwe +8.7. Inorongwa senyeredzi duku yeB9.  Mubvunzo: Iyi inyeredzi yorudzii?
Iyi inyeredzi inochinja yerudzi rweBeta Cephei
