# The Sun as a probe of Fundamental Physics and Cosmology

## TL;DR

This paper discusses how the Sun, modeled through helioseismology and neutrino data, serves as a tool to investigate fundamental physics and dark matter properties, impacting stellar evolution understanding.

## Contribution

It introduces methods using the standard solar model to constrain dark matter candidates and study their effects on stellar evolution in high dark matter density regions.

## Key findings

- Standard solar model accurately predicts the Sun's internal structure.
- Helioseismology and neutrino data constrain dark matter properties.
- Dark matter influences stellar evolution in dense regions.

## Abstract

The high quality data provided by helioseismology, solar neutrino flux measurements, spectral determination of solar abundances, nuclear reactions rates coefficients among other experimental data, leads to the highly accurate prediction of the internal structure of the present Sun - the standard solar model. In this talk, I have discussed how the standard solar model, the best representation of the real Sun, can be used to study the properties of dark matter, for which two complementary approaches have been developed: - to limit the number of theoretical candidates proposed as the dark matter particles, this analysis complements the experimental search of dark matter, and - as a template for the study of the impact of dark matter in the evolution of stars, which possibly occurs for stellar populations formed in regions of high density of dark matter, such as stars formed in the centre of galaxies and the first generations of stars.
