The Sun and stars: Giving light to dark matter

Abstract

During the last century, with the development of modern physics in such diverse fields as thermodynamics, statistical physics, and nuclear and particle physics, the basic principles of the evolution of stars have been successfully well understood. Nowadays, a precise diagnostic of the stellar interiors is possible with the new fields of helioseismology and astroseismology. Even the measurement of solar neutrino fluxes, once a problem in particle physics, is now a powerful probe of the core of the Sun. These tools have allowed the use of stars to test new physics, in particular the properties of the hypothetical particles that constitute the dark matter of the Universe. Here we present recent results obtained using this approach

The Effect of Dark Matter on Stars at the Galactic Center: The Paradox of Youth Problem

“…This result is in agrement with the results of the previous studies (e.g. see 12,14,17,[23][24][25][38][39][40][41] ).…”

“…For the first time, Steigman et al had studied the DM effect on the sun as a possible solution to the solar neutrino problem 7 . Since then many studies had conducted to study possible impacts of the DM on the sun [8][9][10][11][12][13][14][15][16] . Later studies (see e.g.…”

Dark matter in galaxies

“…Note, however, that one possible DM candidate particles are the so-called asymmetric weakly interacting particles (the symmetry is in unequal amount of particles and anti-particles), which, like WIMPs, have a very small interaction cross-section with baryons. A tiny fraction of these particles can, by being scattered when flying through stars, lose the kinetic energy and to store during a long time in the very center of stars thus affecting the process of energy generation and transport (see[351] and references therein).…”
