  The energy sources of the Sun may actually involve a thermonuclear runaway
energy source present in stellar energy producing regions. I consider the
conjectures of the derived model for the solar neutrino fluxes in case of a
solar core allowed to vary in relation to the surface activity cycle. The
observed neutrino flux data suggest a solar core possibly varying in time. In
the dynamic solar model the quiet and runaway energy sources together may
produce quasi-constant flux in the SuperKamiokande because it is sensitive to
neutral currents, axions and anti-neutrinos, too. I calculate the contributions
of the runaway source to the individual neutrino detectors. The results of the
dynamic solar core model suggest that since the HOMESTAKE detects mostly the
high energy electron neutrinos, therefore the HOMESTAKE data may aniticorrelate
with the activity cycle. Activity correlated changes are expected to be present
only marginally in the GALLEX and GNO data. The gallium detectors are sensitive
mostly to the pp neutrinos, and the changes of the pp neutrinos arising from
the SSM-like core is mostly compensated by the high-energy electron neutrinos
produced by the hot bubbles of the dynamic energy source. The results suggest
that the GALLEX data may show an anti-correlation, while the SuperKamiokande
data may show a correlation with the activity cycle. Predictions of the dynamic
solar model are presented for the SNO and Borexino experiments which can
distinguish between the effects of the MSW mechanism and the consequences of
the dynamic solar model. The results of the dynamic solar model are consistent
with the present heioseismic measurements and can be checked with future
heioseismic measurements as well.
