Seismic view of the solar interior [PDF]

Journal of Astrophysics and Astronomy, 2002
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

Solar interior models

, 1991
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 ...

Solar Interior Rotation and its Variation

Living Reviews in Solar Physics, 2009
This article surveys the development of observational understanding of the interior rotation of the Sun and its temporal variation over approximately forty years, starting with the 1960s attempts to determine the solar core rotation from oblateness and ...

The solar interior

2001
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

2018
We 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.

Helioseismology and the solar interior dynamics

Journal of Astrophysics and Astronomy, 2000
AbstractThe 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.

Present problems of the solar interior

Solar Physics, 1985
The 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.

Rapid Rotation of the Solar Interior

Science, 1967
A 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.

The Solar Interior

2019
Neutrinos allow us to look into the interior of the Sun, in particular by observing the neutrino fluxes that come from the Sun’s core, which yield stringent tests whether we understand the nuclear physics and calculate the correct temperatures and densities in solar or stellar cores.
