A pulsating ejecting solar core model and the solar neutrino problem

It is pointed out that the solar neutrino problem is related to a remarkable series of astrophysical problems of the solar core. Even if the MSW effect in itself would be able to give account of the missing neutrinos, one could explain the possible time variation of the neutrino flux (as revealed by the chlorine solar neutrino experiment) only by a non-standard solar model, allowing time-dependent density variations in the core. For resolving all these problems, I suggest that the Sun does not work as a well-tempered fusion reactor, and I present a mechanism which can generate the solar activity by the core. Changing the commonly accepted hypothesis from the constancy of the solar core into its variation with the activity cycle under the pressure of newly accumulating evidences, here I explore some consequences of this theoretically and observationally supported assumption, also to the observed neutrino fluxes. Allowing very localized time varying densities, i.e. the presence of macroscopic flows, a simple mechanism is derived for the generation of local thermonuclear runaways in hot bubbles shooted out from the core. The model derived seems to be also appropriate for the interpretation of a whole list of tantalizing problems like the nitrogen enigma, the flare related chemical anomalies, the heavy element enhancement of the solar corona and the rigid rotation of the activity generating centres.
