Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Spectrum yenyeredzi iyi inowirirana nekugoverwa kwenyeredzi kweK2 III Ca-1, nekirasi yechiedza cheIII inoratidza kuti inyeredzi huru yakashanduka iyo yapedza kupihwa kwehydrogen mukati mayo uye ikozvino iri pabazi dzvuku hombe. Chikamu che'Ca-1' chokurongwa chinoratidza kuti chinoratidza mitsetse yecalcium isina kusimba kupfuura yenguva dzose muvara racho. Kubvira muna 1943, chitarisiko chenyeredzi iyi chave chiri chimwe chezvinhu zvinonyatsozivikanwa zvinoshandiswa pakuronga dzimwe nyeredzi. Kunofungidzirwa kuti ine chinenge 50% chakakura kupfuura Zuva, nepo kuyerwa kweinterferometric kunoratidza kuti yakakura kakapetwa kagumi nemashanu muhukuru. Pasinei nehupamhi hwayo hwakawedzerwa, nyeredzi iyi ichiri kutenderera nekumhanyisa kweazimuthal equatorial kupfuura Zuva, iine fungidziro yekumhanyisa kutenderera kwe3.44 km s-1.Hamal iri kupenya kanokwana ka91 kupenya kweZuva kubva kumhete yayo yekunze pane tembiricha inoshanda ye4,480 K. Izvi zvinotonhora kupfuura pamusoro peZuva, zvichimupa kupenya kweorenji kweK-mhando nyeredzi. Kunofungidzirwa kuva kunochinja-chinja zvishomanene, neukuru hwesimba re 0,06. Kuwanda kwezvimwe zvinhu kunze kwehydrogen nehelium, izvo vanoongorora nyeredzi vanodana kuti metallicity yenyeredzi, ingori hafu yeiyo iri muZuva. Muna 2011, kuvapo kwepasi kunotenderera kunotenderera nyeredzi iyi kwakataurwa naByeong-Cheol Lee et al. Yakaonekwa ichishandisa nzira ye radial velocity, zvichibva pakuyera kwakaitwa pakati pa2003 na2010 paBohyunsan Optical Astronomy Observatory muKorea. Chinhu chacho chine nhambo yokumativi enyika yamazuva 381 uye eccentricity ye0.25. Muganhu wepasi pahuremu hwechinhu ichi unenge ka1.8 huremu hwaJupiter. Semi-major axis inofungidzirwa yenzira yepasi ndeye 1.2 astronomical units (AU), iyo yaizopa iyo periapsis kure kwe0.9 AU uye apoapsis kure kwe1.5 AU. Mukuenzanisa, nyeredzi ine nharaunda ye0.07 AU.  Mubvunzo: yakawanda zvakadini nguva yakawanda iri uremu hwechinhu pamuganhu wepasi?
