Hei tauira, ko te nuinga o nga whetu i raro i te 0.3 solar masses he tino taurangi, ko te tikanga kaore he rohe radiative. Mai i te 0.3 ki te 1.2 solar masses, ko te rohe huri noa i te uara o te whetu he rohe radiation, i wehe mai i te rohe taurangi o runga ake e te tachocline. Ko te radius o te rohe radiative ka piki haere me te papatipu, me nga whetu huri noa i te 1.2 solar masses e tata ana ki te papatipu. I runga ake i te 1.2 solar masses, ka waiho te rohe matua hei rohe taurangi, ko te rohe o runga ake he rohe radiation, me te nui o te papatipu i roto i te rohe taurangi me te nui o te papatipu o te whetu.
te taumaha o te whetū.
