?The solar wind contents
« on: 07/11/2011 17:24:40 »
There is a lot of data from NASA on the solar wind and it appears to consist mostly of positively charged ions of hydrogen with some traces of helium and other + ions.   
We are also told that there is a stream of electrons coming off the sun.
My question is why don't these +ions and -electrons interact in a normal way and balance up as a molecule of free gas??

The solar wind is a plasma.  That is its general charge is neutral that is the positive charge on the ions is balanced out by the negative charge on the electrons although they may move differently under the effect of magnetic and electrical fields.  In general the electrons are just assumed to be there and the main interest is the composition of the positive ions.

The reason that they do not combine is that they are all too hot, that is moving randomly with too high a speed to combine with each other.  The solar wind is complex with several different components and sources with temperatures of the particles in the region of one million degrees K.
