Helioseismology and solar neutrinos: an update
Helioseismology has added important data on the solar structure which provide severe constraint and tests of SSM calculations. For instance, helioseismology accurately determines the depth of the convective zone Rb and the photospheric helium abundance Yph. With these additional constraints there are essentially no free parameters for SSM builders. In this paper we review recent advances concer...
متن کاملImaging the Solar Tachocline by Time-Distance Helioseismology
The solar tachocline at the bottom of the convection zone is an important region for the dynamics of the Sun and the solar dynamo. In this region, the sound speed inferred by global helioseismology exhibits a bump of approximately 0.4% relative to the standard solar model. Global helioseismology does not provide any information on possible latitudinal variations or asymmetries between the North...
متن کاملHelioseismology and Screening of Nuclear Reactions in the Sun
We show that models for screening of nuclear reactions in the Sun can be tested by means of helioseismology. As well known, solar models using the weak screening factors are in agreement with data. We find that the solar model calculated with the anti screening factors of Tsytovitch is not consistent with helioseismology, both for the sound speed profile and for the depth of the convective enve...
متن کاملValidation of Time-distance Helioseismology by Use of Realistic Simulations of Solar Convection
Recent progress in realistic simulations of solar convection have given us an unprecedented opportunity to evaluate the robustness of solar interior structures and dynamics obtained by methods of local helioseismology. We present results of testing the time-distance method using realistic simulations. By computing acoustic wave propagation time and distance relations for different depths of the...
متن کاملHelioseismic tests of diffusion theory
We present a quantitative estimate of the accuracy of the calculated diffusion coefficients, by comparing predictions of solar models with observational data provided by helioseismology. By taking into account the major uncertainties in building solar models we conclude that helioseismology confirms the diffusion efficiency adopted in SSM calculations, to the 10% level.
