Hi there,
I have a question regarding the life cycle of a star. I know that when entering the red giant phase of a star's life, its radius/overall size will increase dramatically, but I was wondering if there's a basic way to determine the factor it will grow by during this process.
I've seen predictions for our Sun's expansion range from 100x its current radius to 200x its current radius, but the considerable difference between these two measurements left me skeptical.
Is there a formula to determine (even an approximation of) what a star's radius as a red giant may be?
