A Dynamic Solar Core Model: the SSM-like solution

چکیده

I point out that all the arguments available in the literature against an astrophysical solution of the solar neutrino problem(s) do not exclude a yet not recognised class of solar models, in which an explosive energy source is present in the solar core besides the standard proton-proton and CNO cycle. It is shown from first principle physics that stars have a non-equilibrium energy source as well, arising from transient local thermonuclear runaways. I derive a model independent inequality, which shows that the problem of the missing beryllium neutrinos lies in that the SuperKamiokande contains a term arising from neutrinos of a non-pp,CNO source. Recent indications suggest strongly that this term plays a more significant role in the solar neutrino problem than neutrino oscillations. The runaways can produce high-energy electrons and high-energy axions, and may produce muon and tau neutrinos above 10 K, and electron antineutrinos. I show that subtracting the runaway term from the SuperKamiokande results the remaining data are compatible with each other, within the frame of a generalised luminosity constraint and standard neutrinos. Allowing non-pp,CNO reaction chains a new approach arises to interpret the neutrino detector data, opening new horizons to solar neutrino astrophysics. I point out, that the temperature dependence of the individual neutrino fluxes is related to pure nuclear physics, but the usual luminosity constraint is model dependent and actually is a questionable assumption. The explicit temperature dependence leads to Φpp ∝ T 4 for the more general case instead of the usual Φpp ∝ T −1/2 for the SSM luminosity constraint. I assume a Sun analogue to the SSM, in the sense that the actual, average temperature can be described by a single parameter, in terms of the SSM temperature. This is the ”SSM-like solution” of the neutrino-flux equations.

v 1 4 N ov 1 99 6 STANDARD PHYSICS SOLUTION TO THE SOLAR NEUTRINO PROBLEM ?

The 8 B solar neutrino flux predicted by the standard solar model (SSM) is consistent within the theoretical and experimental uncertainties with that observed at Kamiokande. The Gallium and Chlorine solar neutrino experiments, however, seem to imply that the 7 Be solar neutrino flux is strongly suppressed compared with that predicted by the SSM. If the 7 Be solar neutrino flux is suppressed, st...

A dynamic solar core model: on the activity-related changes of the neutrino fluxes

I point out that the energy sources of the Sun may actually involve runaway nuclear reactions as well, developed by the fundamental thermonuclear instability present in stellar energy producing regions. In this paper 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 neutri...

Standard Solar Neutrinos and The Standard Solar Model

The standard solar model (SSM) yield a 8B solar neutrino flux which is consistent within the theoretical and experimental uncertainties with that observed at SuperKamiokande. The combined results from the SuperKamiokande and the Chlorine solar neutrino experiments do not provide a solid evidence for neutrino properties beyond the minimal standard electroweak model. The results from the Gallium ...

What Hides at the Center of the Sun ?

The Standard Solar Model (SSM) and its basic assumption of an equation of state of perfect gases for the plasmas of its interior is analyzed within the new theoretical framework of QED coherent states. We find that for r r ⊙ ≤ 0.3 the SSM solution is unstable against collapse to a dense, cold coherent core and as a result a large suppression of B 8-neutrinos is obtained, apparently solving the ...

Testing the LMA solution with solar neutrinos independently of solar models

We perform a comparative study of two methods of determining the survival probabilities of low, intermediate, and high energy solar neutrinos that emphasizes the general agreement between the Large Mixing Angle (LMA) solution and extant solar neutrino data. The first analysis is oscillation parameter-independent and the second analysis involves an approximate calculation of the survival probabi...
