Sunspots, areas of intense magnetic fields.

Click For Summary

Discussion Overview

The discussion revolves around sunspots, specifically their nature as areas of intense magnetic fields and their potential role in nuclear reactions and the formation of heavier elements. Participants explore various hypotheses regarding the conditions and mechanisms associated with sunspots, including their temperature, magnetic properties, and formation locations.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that sunspots could act like a natural Tokamak, potentially trapping core material from the sun and facilitating nuclear reactions to produce elements heavier than iron.
  • Others argue against this idea, suggesting that any core material would be too energetic for sunspot magnetic fields to contain, leading to a spillover before reactions could occur.
  • One participant raises the possibility that the twisted nature of magnetic fields in sunspots could create high pressures during explosive events, possibly leading to coronal ejections.
  • There is a discussion about the temperature of sunspots, with some noting that they can be several hundred degrees cooler than the surrounding photosphere, questioning the assumption that they are hotter.
  • Some participants agree on the intensity of magnetic fields in sunspots but clarify that these fields are not as strong as those found in a tokamak.
  • A question is posed regarding the specific locations where sunspots form and whether those areas exhibit unique properties that contribute to their formation.

Areas of Agreement / Disagreement

Participants express differing views on the potential for sunspots to serve as sites for nuclear reactions and the storage of heavier elements. While some agree on the characteristics of sunspots, there is no consensus on their role in elemental formation or the mechanisms behind their properties.

Contextual Notes

Limitations include the lack of consensus on the mechanisms of nuclear reactions in sunspots and the specific conditions required for their formation. The discussion also reflects uncertainty regarding the comparative strength of magnetic fields in sunspots versus tokamaks.

Who May Find This Useful

This discussion may be of interest to those studying solar physics, astrophysics, or anyone curious about the magnetic properties of the sun and their implications for elemental formation in the solar system.

Sunspots are areas of intense magnetic fields. They are supposed to be hotter than the surface of the sun but are darker because of decreased convection with the interior of the sun.

Is it possible for these fields to trap matter from the sun's core and magnetically confine it at enormous heat and pressure? (nature's Tokamak) If so, could nuclear reactions to produce elements heaver than iron be possible? Could the sunspots be a source of some of the material heavier than helium in our solar system?

Interesting idea and i really don't know but id imagine not, as any core material brought up would be far more energetic than even a sunspots magnetic field could contain and it would spill out before any reactions could occur.
 
The field is supposed to be highly twisted. Like a garden hose with kinks? Could matter back up and create huge pressures during an explosive event that manifests itself on the surface, eventually, as a coronal ejection?
 
Why do you think they are hotter? The temperature can be several hundred degrees below that of the surrounding photosphere.
 
Yeah, you are right about that.
 
You are correct, however, about the intense fields in sunspots. But they aren't anywhere near the strength of a tokamak.
 


I just came across this thread...Has anyone been able to find out the answer to this?? Could anyway the sunspots be a store of heavier elements?
 


I don't believe so. As country boy says above, sunspots simply don't work that way.

Sir...How can we say that the they aren't anywhere near the strength of a tokamak?? Is there any reason behind this??

If you don't think am deviating from the topic, why do sunspots form only at some places? what are the requirements, actually?? what I mean is..are there any special properties those places do exhibit which make them to be sunspots?
