Here is a really good description of the processes, fuel, and resultant sizes during the life of our sun. :-)

I haven't looked into it deeply either. Just parts of that article struck me wrong. I will do a bit of research and get back to you.

My very best regards,

That's right, and Mars as well. The planets within the sun's atmosphere would evaporate. This will be in five billion years or so, but it might be well to consider that it will be getting warm on earth well before then and the oceans will have boiled off four billion years earlier.
