Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Iyi inyeredzi hombe ine marongerwe enyeredzi eK4 III. Rinopenya kakapetwa ka130 kupfuura Zuva. Kochab yasvika padanho mukushanduka-shanduka kwayo apo goko rayo rokunze rakakura kusvika kuukuru hunopetwa ka42 kupfuura hweZuva. Iyi mhepo yakakura iri kupenya zvakapetwa ka390 kupfuura kupenya kweZuva kubva mumhepo yayo yekunze pane tembiricha inoshanda ye4,030 K. Kupisa uku kunopa nyeredzi kupenya kweorenji-kweyeredzi yeK-mhando.Nekuenzanisira nyeredzi iyi zvichibva pakushanduka-shanduka, huwandu hweiyi nyeredzi hunogona kufungidzirwa se2.2 ± 0.3 yeiyo yeZuva. Kuyerwa kwehuremu uchishandisa interferometrically-yakayerwa nharaunda yenyeredzi iyi uye spectroscopically-yakatarwa pamusoro pesimba rinokwevera rinopa 2.5 ± 0.9 masasi ezuva. Nyeredzi inozivikanwa kuti inochinja-chinja nguva nenguva mukuvhenekera kwemazuva anenge 4.6, nemaitiro eastroseismic anoenderana nehukuru hwenyeredzi. Kubva pane izvi, kuyerwa kwakaderera kwazvo kwe1.3 ± 0.3 solar kunosvika.  Mubvunzo: Nyeredzi huru dzinorongwa sei?
