The fusion level from the Main is within a self-correcting equilibrium: a slightly greater rate of fusion would induce the Main to heat up much more and expand a little bit from the load in the outer layers, reducing the density and as a result the fusion amount and correcting the perturbation; and a slightly lower level would bring about the Main to chill and shrink marginally, expanding the density and rising the fusion rate and once more reverting it to its present rate.[73][74] Radiative zone
