I'm looking for a star system between 15 and 36 ly from Sun with these characteristics:
- composed by 2 or more stars
- one of the stars should be a late G/ K type star (it doesn't matter for the other/s)
- both should have at least 2.5 AUs of stability for planets
- maximum distance beetween stars: less than 150/200 AUs
If it's possible (but this is a plus), the stars should be not very young and have a few known/colonisable stars near them. If a planet orbiting them would a circumbinary orbit it is also ok. A brown dwarf doesn't count as star.
I want to put 1 or 2 planet(s) in the habitable zone of one star. Which would be the best star systems with these characteristics from 15 to 36 light years from Sun?
A good answer should include at least 2 star systems, the reasons why you've chosen them and the source of the data.
