Abstract This report confronts the different aspects of the solar interior from the experimental and theoretical points of view, discussing photospheric abundances, neutrinos and acoustic mode measurements. The theoretical approach mainly concerns the classical framework of stellar evolution, nevertheless, particle interpretation of the data and ...

Seismic view of the solar interior [PDF]
The interior of the Sun is not directly observable to us. Nevertheless, it is possible to infer the physical conditions prevailing in the solar interior with the help of theoretical models coupled with observational input provided by measured frequencies of solar oscillations. The frequencies of these solar oscillations depend on the internal structure

The interior properties of four solar models from the recent astrophysical literature are presented. The first three are standard solar models, each with somewhat different input physics. The fourth is an unconventional model designed to address the solar neutrino problem, with reduced central opacity to simulate the effects of weakly interacting ...

The quest to learn the internal structure and dynamics of the Sun is motivated by several issues. For most people the most obvious is the desire to understand the source of energy for the Earth, which is essential for the maintenance of life. Astronomers are interested in the Sun because it is an example of a typical main-sequence star that can be ...

Solar neutrinos and nuclear reactions in the solar interior
2018We discuss the results of Homestake and Kamioka experiments, showing that - if the results of these experiments are taken at their face values - one way to save "conventional neutrinos" is to look for a nuclear solution decreasing both 7Be and 8B neutrino fluxes with respect to the predictions of the standard solar models.

Present problems of the solar interior
Solar Physics, 1985The standard model of solar evolution is reviewed and a number of problems highlighted. A fundamental question is whether there is any mixing of matter in the central regions, since such mixing could radically alter the model of the present Sun and modify our understanding of the evolution of other stars.

Helioseismology and the solar interior dynamics
Journal of Astrophysics and Astronomy, 2000AbstractThe inversion of helioseismic modes leads to the sound velocity inside the Sun with a precision of about 0.1 per cent. Comparisons of solar models with the “seismic sun” represent powerful tools to test the physics: depth of the convection zone, equation of state, opacities, element diffusion processes and mixing inside the radiative zone.

Rapid Rotation of the Solar Interior
Science, 1967A model proposed for the sun apparently can account for the maintenance of photospheric rotation against deceleration by the solar wind. The rotational period is about half a day near the top of the radiative mass, and 1.6 times shorter at the center.
