Standard Solar Model

AIP Conference Proceedings, 2008
Solar models are important in our understanding of stars and stellar evolution. Solar models have been constructed using different methods. In this work, a solar model will be built using the fitting method. The model will incorporate the most recent input data.

Standard and Non-Standard Solar Models

Solar Physics, 2001
We summarize the physical input and assumptions commonly adopted in modern standard solar models that also produce good agreement with solar oscillation frequencies. We discuss two motivations for considering non-standard models: the solar neutrino problem and surface lithium abundance problem. We begin to explore the potential for mixed core models to

Solar abundances, convection and the standard solar model

2008
A new observed Z/X ratio is proposed for the Sun. We apply it to recalibrating the Sun with two different convection theories, the classical MLT and the recent theory of Canuto and Mazzitelli.

Shortcomings of the Standard Solar Model

Space Science Reviews, 1998
The SSM, invented in early nineteen sixties, remains a useful construction. There are now much larger number of its predictions that may be compared with observations than when it was first introduced. Seismic sounding based on oscillations frequencies provides the best test of the physical input for modelling stellar evolution. The results of the test

Matter-enhanced neutrino oscillations in the standard solar model

Physical Review D, 1989
The effects of matter-enhanced neutrino oscillations on solar-neutrino experiments can be calculated accurately only if uncertainties in the standard solar model are treated properly. As the oscillation probability depends on the neutrino energy, while modifications in the parameters of the standard solar model produce correlated changes in the various

The standard solar model for the solar neutrino problem

Nuclear Physics B - Proceedings Supplements, 1995
A thorough analysis of the low energy nuclear data pertinent to the nuclear reactions in the Sun and the solar neutrino problem leads to significant modifications in the most. important cross sections and to a new estimate for the solar neutrino flux.

Metallicity, opacity coefficients and the solar standard model

Solar Physics, 1990
We discuss the effect of the uncertainties affecting the opacities on the derived characteristics of the Sun. We consider two sources of uncertainty: the relative composition of the Sun at birth and the difference between two opacity calculations. As an illustration, we discuss the effect of the choice of photospheric or meteoritic iron abundance on ...

Solar neutrino oscillations in extensions of the standard model

Physical Review D, 2000
The solar neutrino oscillations are considered within the left right model and the general two Higgs doublet model. The study makes it apparent that the interactions between leptons and the physical Higgs bosons could significantly influence the oscillations pattern.
