Scientific paper

The influence of dark gravitating matter on the present-day Sun and its evolution is studied. Numerical simulations show that substantial departures of the main model parameters (luminosity, effective temperature, neutrino flux, and age) from the modern solar parameters would occur if the relative mass of dark matter exceeded 2 5% of the solar gravitational mass. The flux of solar neutrinos is relatively insensitive to the presence of uniformly distributed dark matter. However, a strong concentration of dark matter toward the center of the Sun would increase the neutrino flux beyond the observational limits.
