Dark Matter

Heart of darkness could explain sun mysteries - New Scientist
Their simulations show that gravity would pull such dark particles to the centre of the sun, where they would absorb heat. Some of these dark matter particles would then carry this heat from the core to the surface, decreasing the core temperature

[1005.5102] Light WIMPs in the Sun: Constraints from Helioseismology
Our main conclusion demonstrates that both direct detection experiments and particle accelerators may be complemented by using the Sun as a probe for WIMP dark matter particles in the 5-50 GeV mass range.
