Web7 hours ago · The convective envelopes of solar-type stars and the convective cores of intermediate- and high-mass stars share boundaries with stable radiative zones. Through a host of processes we collectively refer to as “convective boundary mixing” (CBM), convection can drive efficient mixing in these nominally stable regions.

Solved How does the CNO cycle differ from the proton-proton
WebCNO cycle operates near the solar surface, where H, He, C and N are abunda nt [1], rather than in the Sun's interior. Rare isotopes of carbon and nitrogen,13C and 15N, are produced by reactions 2 and 5 in the CNO cycle outlined above. In 1975 Kerridge [7] noted that the 15N/14N ratio in the solar wind appears to have increased over geologic time.
