How much dark matter is in the Sun, and does it have any

  1. Jul 17, 2010 #1
    How much dark matter is in the Sun, and does it have any effect on any process in the Sun?
    What percent of the total mass and volume of the Sun is DM by weight, and by volume?
    Does the high density of the Sun impede movement of DM? Is there a lot of DM trapped by the Sun's gravitational field? Does DM couple in fusion process or cool off the Sun?

    The sun shouldn't have any significant dark matter (depending on which dark matter theory you like)

    There is not very much Dark Matter, and it has no influence on the sun's evolution. I don't know the percentage offhand, but it's in the region 10^-27.
    Yes, but only in the form ofhttp://en.wikipedia.org/wiki/Xeelee_Sequence_species#Photino_birds".

    Since we don't know what particles make up dark matter and how these particles react with each other and with ordinary matter, we really don't know the answer to this question. There have been some recent papers (http://arxiv.org/abs/1003.4505v2, http://arxiv.org/abs/1005.5102v1) that there could be enough dark matter in the sun to measurably affect the fusion and energy transfer rates. Stay tuned...
