The beast wrote-

Which still leaves Brian hanging, though it brings up an interesting
question: does an M-class(whatevertheheckthatREALLYmeans) require a near
G0
star, or can you put a planet with heavy atmosphere in a further orbit
around a hotter star, or lesser atmosphere in a near orbit to a cooler
one?
I seem to recall interesting speculations on radiation
other-than-light-heat, and year lengths. If this is TOO OT, let me know.

I would like a answer to this as well. I remember from some of my sci-fi
novels, a area of habitablity is a certain distance from each star, and
the
hotter the star, the further away the habital zone is. For dim stars,
the
habital zone is too close, and a planet will become tidelocked to the
star,
meaning a habitable biospere would be imposible. Also, the next is pure
speculation, but I think a stable, breathable atmosphere would be
imposible
too close to a star due to cronal discharge (solar winds and sunspot
discharges). The above is waiting for correction from somebody who
actually
knows what they are talking about <G>.
