RESUMO

We analyse a model where slow magnetosonic waves are produced from solar plasma displacements perturbating the solar magnetic field. As a consequence, when a nonvanishing neutrino magnetic moment is assumed, we observe flutuations of solar neutrino flux. This is because the interaction of solar neutrinos with the perturbated solar magnetic field leads to a conversion of an active neutrino into a nondetectable one. We solved the equation that models the perturbated solar magnetic field and the evolution equations of neutrinos interacting with the solar magnetic field. We simulate the time behavior of 8B solar neutrino spectrum to analyse possible flux fluctuations which will be detailed observed in experiments will begin operating in a near future
