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

Click For Summary

Discussion Overview

The discussion centers on the presence and potential effects of dark matter (DM) within the Sun, exploring questions about its mass contribution, influence on solar processes, and the implications of various dark matter theories. The scope includes theoretical considerations and speculative implications for solar evolution.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions how much dark matter is present in the Sun and its effects on solar processes, including fusion and energy transfer.
  • Another participant suggests that the Sun should not contain significant dark matter, depending on the dark matter theory considered.
  • It is mentioned that dark matter's presence in the Sun is minimal, with estimates around 10^-27, and that it does not influence the Sun's evolution.
  • There is a claim that dark matter could couple in fusion processes, but this is presented with uncertainty and references to speculative concepts.
  • A later reply highlights the unknown nature of dark matter particles and their interactions, suggesting that recent research may indicate measurable effects on fusion and energy transfer rates in the Sun.

Areas of Agreement / Disagreement

Participants express differing views on the significance of dark matter in the Sun, with some asserting its negligible influence while others suggest potential measurable effects based on recent research. The discussion remains unresolved regarding the exact implications of dark matter in solar processes.

Contextual Notes

Limitations include the unknown nature of dark matter particles, their interactions with ordinary matter, and the reliance on various dark matter theories, which may affect the conclusions drawn.

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...
