Dark Matter Particles as Inhibitors of the Solar Core Pulsations

Dark matter particles may be the solution to both the missing mass problem and the solar neutrino deficiency. It has been recently argued that the so-called cosmions may induce an instability inside the solar core, precluding any interpretation of the solar neutrino puzzle in terms of weakly interacting massive particles. This work reaches the opposite conclusion. Cosmions act to favor the vibrational stability of the solar core. In the presence of cosmions the amount of energy which feeds the solar pulsations is globally negative, inhibiting their development. This analysis differs from the earlier treatment since it deals with the entire region of the solar core where the CDM particles dominate the heat transport and does not concentrate only on the very center of the star.
