T-Bird originally posted the article.
I don't know the source.

Good point.
If we are talking about friction, then we need to have some idea as to the density of the plasma (ionized atoms per cubic metre) in those outer regions of the heliopause (limit of the sun's influence).

Also (from memory), the sun is travelling towards the star Vega at around 20 miles per second and I wonder whether the impact on the atoms in that area, with those of interstellar space, would be sufficient to cause a glow.

I would say alternatively however, that at those outer limits of the heliopause, there may exist what is known as a "cathodic drop" region where the extreme limit of the sun makes contact with interstellar space.

It has been estimated that at this point, in the case of the sun, the cathode drop is something of the order of 10 billion volts and perhaps is enough in itself to cause a glow.

It could be that the sun is actually moving into a much higher energetic region of interstellar space, because the star Vega is twice as hot and far more energetic than the sun.

What I am implying here is that maybe it is the different regions of interstellar space that actually determine how a star behaves.

Hence we have stars of many different types, from dwarfs right up to supergiants and beyond, each behaving accordingly to the local environments in which they exist.
