| Resumo: | The study of solar neutrinos is very important to a better comprehension of the set of
nuclear reactions that occurs inside the Sun and in solar type stars. The
ux of neutrinos
provides a better comprehension of the stellar structure as a whole. In this dissertation
we study the
ux of neutrinos in a solar model, addressing the neutrino oscillation, analyzing
with the intention of determining and verify the distribution from a statistical point
of view, since this
ux depends on the particles intrinsic velocity distributions in stellar
plasma. The main tool for this analysis was the Toulouse-Geneva Stellar Evolution Code,
or TGEC, which allow us to obtain the neutrino
ux values per reaction and per layer
inside the Sun, allowing us to compare the observational results for the neutrino
ux detected
on experiments based on Cl37 (Homestake), Ga71 (SAGE, Gallex/GNO) and water
(SNO). Our results show the nal distribution for neutrino
ux as a function of the depth
using the coordinates of mass and radius. The dissertation also shows that the equations
for this
ux are present in TGEC. |
