Nonlinear Density Enhancement of ³He in the Sun’s Central Core

A flow velocity field that has a “sink” drives the core ³He nuclear reaction diffusion system to instability to jump from the original state to the new one, in which the total amout of ³He is enhanced. This alters the original competition between pp I and pp II +pp III chains, and thus potentially suppresses the production of both the ⁷Be and ⁸B neutrino fluxes.
