Even if BY Draconis appears to be slightly colder than Sun, I doubt you could get an inhabitable planet so close to it. And the two main stars appears to be so close between them that planets around them probably just get the same pull as they would get from a single object at their barycenter. | |

In theory, by eliminating the moon and making the planet's day equal to a full year (i.e., the same side of the planet always faces the star it orbits), you could minimize volcanic activity to below the noise level. But, given that you have a binary star, that is not possible. | |
