What about the type K stars?
We live on a planet circling a type G main-sequence yellow dwarf star. In our region of space, about 7.5% of the stars are type G. Everybody talks about the type M red dwarfs. That's reasonable: there are a lot of them, about 76% of the stars in our neighborhood. But they don't give out much light. For a planet to be in the Goldilocks Zone, it has to be quite close to the star. It's probably tide-locked. Worse, red dwarfs are given to tantrums, with flares and radiation. I wouldn't want to live next to one.
Why is nobody talking about the type K orange dwarfs? They make up about 12% of the stars in our neighborhood. They're heavier than the red dwarfs, and give off more light -- and they're not nearly as excitable as the red dwarfs. There'd be more mass in the system, the planets would probably be larger, and they'd have more of a chance to keep their atmosphere. Why, they might not be tide-locked, even!
I certainly hope it's because everybody is so busy talking about the planets they don't bother going into fine detail about the stars.
