Kepler related question

Basilisk

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.

something like this?

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.
