RESUMO

We argue that solar neutrino observations should be sensitive to the magnetohydro-dynamics fluctuations in the Sun if the Resonant Spin-Flavor Precession mechanism is a solution to the Solar Neutrino Problem. Our calculations show the existence of global and localized magnetohydrodynamic waves with a period of the order of 1 to 10 days and we study their consequences on solar neutrino flux detected at the Earth. We concluded that magnetohydrodynamic perturbations induce fluctuations on the solar neutrino flux with the mentioned period and they take the appearance of effects of parametric resonance for neutrinos which energy is of order 0.1 to 1 MeV. These effects can be used to test the mechanism of Resonant Spin-Flavor Precession
