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

In summary, the amount of dark matter present in the Sun is very small, estimated to be around 10^-27 in both weight and volume. It does not have any significant impact on the Sun's evolution. It is possible that dark matter could play a role in the fusion process, but since we do not know the properties of dark matter, it is currently unknown how it would affect the Sun. Recent studies suggest that there could be enough dark matter in the Sun to potentially affect fusion and energy transfer rates, but further research is needed to confirm this.

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".

:D

I love Baxter, that's the first thing I thought of too when I saw the thread.

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...

1. How do scientists measure the amount of dark matter in the Sun?

Scientists measure the amount of dark matter in the Sun indirectly, by observing the effects of its gravitational pull on other objects in the solar system. This is known as gravitational lensing.

2. What is the estimated amount of dark matter in the Sun?

The estimated amount of dark matter in the Sun is very small, around 0.00001% of its total mass. This is because dark matter is thought to be spread out throughout the universe, rather than being concentrated in one particular location.

3. Does dark matter have any influence on the Sun's behavior?

No, dark matter does not have any direct influence on the Sun's behavior. It does not interact with normal matter, including the particles that make up the Sun, except through gravity.

4. How does the amount of dark matter in the Sun compare to other objects in the universe?

The amount of dark matter in the Sun is relatively small compared to many other objects in the universe. For example, dark matter makes up about 27% of the total mass of the universe, while normal matter (such as stars and galaxies) makes up about 5%. This means that there is much more dark matter in the universe than there is in the Sun.

5. Is there any evidence to suggest that the Sun does not have any dark matter?

There is currently no evidence to suggest that the Sun does not have any dark matter. However, scientists are still studying and trying to understand the nature and behavior of dark matter, so our understanding of it may change in the future.
