SUMMARY

The discussion centers on the search for habitable binary star systems within the Kepler catalog, specifically those where a secondary star has a fixed orbit around a primary star. The user seeks systems with G and K class stars, sufficient orbital space for a habitable zone, and proximity to our solar system. The inquiry evolves to include triple star systems with a habitable zone around a central binary pair, referencing examples such as HD 188753 and 16 Cygni. The rarity of binary systems with the specified characteristics is acknowledged, indicating a need for further exploration of available resources.

PREREQUISITES
  • Understanding of binary and triple star systems
  • Familiarity with stellar classifications (G and K class stars)
  • Knowledge of habitable zones in astrophysics
  • Experience with the Kepler catalog and its data resources
NEXT STEPS
  • Research the characteristics of habitable zones around binary star systems
  • Explore the Kepler catalog for specific binary and triple star systems
  • Study the orbital mechanics of binary star systems
  • Investigate the implications of stellar classifications on potential habitability
USEFUL FOR

Astronomers, astrophysics students, and anyone interested in the search for habitable exoplanets in binary and triple star systems.

Hi, this is my first post, and it is sort of a complicated question (I think. Perhaps it is easy and I don't know how to solve it).

In the Kepler catalog, are there any binary star systems, where the secondary star orbits the central star that have something close to the following conditions?.

- Can't be like Alpha Centauri where A and B are orbiting around a mass center. I need the secondary star to have a fixed orbit around the primary star (doesn't have to be circular, can be elliptical, the lower the eccentricity the better, though)
- Enough orbital space between the central star and the secondary star orbits to have a habitable zone around the primary star.
- Stars are G and K classes combination (like Alpha Centauri), so there is no photon-cannon around to make carbon based life impossible (no O stars in the vicinity).
- The closest to our Sol system, the better.

Any help will be appreciated.

Also, if there is any good Kepler resource that you guys can point me to, like an online database or such where I can get this information by myself, that would be awesome.

Thanks in advance and sorry for my newbism.

Let me update this. I found that binary stars systems with one star orbiting another are very rare, if not impossible.
So, let me change my question to another kind of star system. I need a triple star system with a habitable zone around the central binary pair, with a third heavier, larger and brighter star orbiting around the central binary pair. Basically, like this:

Thanks again for any tips on the sun's closest stellar system with that setup.

Yeah, they seem interesting. The only thing is that the third star is orbiting too close in one and too far in the other one. But I will look on them. Thanks a lot.
