Red Dwarf Worlds in a Binary System

+0
−0

Scientists seem to be vacillating as to whether a Red Dwarf planet could support life or not. Imagine a G-Type star much like our Sun. Imagine an orbit that would make an Earth-Sized planet warmer than Mars, but noticeably colder than Earth"”Very Marginally habitable.

Now put a Red Dwarf in that orbit and put our Earth-Like Planet in a tidally-locked orbit around the Red-Sun. One side has perpetual Red day. The orbit around the Red Sun should be short"”eight to ten days or so. Yellow days will be four or five days long and then yellow night will be four or five days long.

If our planet is tilted and the orbit around the yellow Sun is eccentric, then we'd have "Meta-Seasons""”lets ignore that for now. Some models suggest that there should be enough atmospheric heat exchanged in a simple Red Sun locked-planet to noticeably warm the dark side.

I'd like to imagine a world where dark side nights are cold, but not as cold as Antarctica whereas the bright side doesn't get drastically hotter during yellow day "” but the photosynthesis increases a great deal during yellow day.

I want reindeer herding nomads on the dark side, hereditary aristocratic plantation owners close to the center (Yeah all models don't feature a perpetual cyclone at the high-noon" position on bright side.) and hillbilly highlander types out towards the edges where the Red Sun hangs low in the sky.

Does anyone see any flaws in the scheme that I haven't seen?
