Re: Are Sunspots Hot?
To JP, Ophiolite & Bored Chemist.
As I have written in my previous post, one form of energy can be converted into another form of energy if losses can be accepted. I have yet to hear how "magnetic energy" can be converted into another form of energy.
A magnetic field is the PROPERTY of an electric current. If someone can provide a way to generate a magnetic field by some other means I would be willing to 'listen' to the misguided theories about "magnetic energy". For me, if a magnetic field exists, certainly when in connection with ionised gases, it must have been created by an electric current. An electric current can only be produced by the expenditure of some form of energy which will certainly not be magnetic.
Around sunspots there is evidence that energy is expended to propel ionised particles away from the sun. I do not and will not rely on any reference in Wikipedia while the Babcock theory is still promulgated by that source.
It is true that magnetic fields can be detected by the Zeemann effect. However, this does not in any way show how they are produced. The main effect of a magnetic field in connection with ionised gases is to constrain a stream of gas which forms the current that creates the magnetic field.
My other main reference book is 'Astrophysical Quantities' by C. W. Allen. In it it states that the strength of the whole magnetic field around a sunspot increases with the area of the sunspot. The figures are consistent with a stream of ionised particles emerging from the sunspot that has a cross sectional area that is proportional to the area of the sunspot.
We observe the effect of the stream of ionised particles coming from sunspots in the aurorae. The magnetic fields around sunspots indirectly indicate that streams of ionised particles emerge from them. We have the circumstantial evidence of what is happening at sunspots. This evidence indicates that SOMETHING makes the ionised particles emerge from sunspots. Whatever it is, it is extremely powerful. As the mean life of a sunspot is around six days, the source must be able to deliver the power consistently for a significant time.
In a simple minded way I presume that because the interior of the sun is an enormous heat generator and that heat causes convection to occur, this could provide an explanation for the emergence of vast streams of ionised particles from sunspots.
My Astrophysical Quantities book does NOT state what the electromagnetic emissions are from sunspots in the extreme ultra short wavelength end of the electromagnetic spectrum. I presume that the energy level in this part of the spectrum is very high but it cannot be detected by instruments currently available. This may be because the sun's atmosphere acts as a shield or for some other reasn.
