Helioseismology and Standard Solar Models
We present a systematical analysis of uncertainties in the helioseismological determination of quantities characterizing the solar structure. We discuss the effect of errors on the measured frequencies, the residual solar model dependence and the uncertainties of the inversion method. We find Y ph = 0.238 − 0.259, R b /R ⊙ = 0.708 − 0.714 and ρ b = (0.185 − 0.199) gr/cm 3 (the index b refers to...
متن کاملConstraining solar abundances using helioseismology
Recent analyses of solar photospheric abundances suggest that the oxygen abundance in the solar atmosphere needs to be revised downwards. In this study we investigate the consequence of this revision on helioseismic analyses of the depth of the solar convection zone and the helium abundance in the solar envelope and find no significant effect. We also find that the revised abundances along with...
متن کاملHelioseismology, Solar Models and Neutrino Fluxes
We present our results concerning a systematical analysis of helioseismic implications on solar structure and neutrino production. We find Yph = 0.238 − 0.259, Rb/R⊙ = 0.708 − 0.714 and ρb = (0.185 − 0.199) gr/cm . In the interval 0.2 < R/R⊙ < 0.65, the quantity U = P/ρ is determined with and accuracy of ±5 ◦/◦◦ or better. At the solar center still one has remarkable accuracy, ∆U/U < 4%. We com...
متن کاملHelioseismology challenges models of solar convection.
C onvection is the mechanism by which energy is transported through the outermost 30% of the sun (1). Solar turbulent convection is notoriously difficult to model across the entire convection zone, where the density spans many orders of magnitude. In PNAS, Hanasoge et al. (2) use recent helioseismic observations to derive stringent empirical constraints on the amplitude of large-scale convectiv...
متن کاملHelioseismology and Solar Abundances
Helioseismology has allowed us to study the structure of the Sun in unprecedented detail. One of the triumphs of the theory of stellar evolution was that helioseismic studies had shown that the structure of solar models is very similar to that of the Sun. However, this agreement has been spoiled by recent revisions of the solar heavy-element abundances. Heavy element abundances determine the op...
