Dark Matter In the center of Sun

[kk434]

Recent findings show that a large quantity of DM is located in the center of the sun, It is affecting the temperature of the core. If this is the case then the Sun may by an entirely different beast then we orginaly thought. Wonder if it is dangerous to have a lot of DM in the center of a star?

I fixed your link for you.

It doesn't say "a large quantity of DM is located in the center of the sun" BTW.

It says "Once gravitationally captured by the Sun, these (DM) particles tend to accumulate in its core."

That's not exactly the same.

Interesting. If the large gravity well of the sun can capture some dark matter particles, it seems likely that the small gravity well of the earth would capture a few (obviously only a small fraction of one percent of what the sun would capture). So there might be a store of dark matter particles on earth, actually in earth. Too bad there probably isn't a way to retrieve those particles from the center of the earth.

Semantics. Pretty much any quantity you deal with in astronomy can reasonably be described as "large."

This sounds like a really interesting result. In fact, it looks from the paper like the basic idea isn't entirely new, and what they do here is use an updated solar model to compute exactly what sort of effect certain types of dark matter particles should have, and what observable signatures those would have. Will be very interesting once the next gen of neutrino observatories comes up and can measure these.
