Aquarius IX is twice as massive as its companion, but about the same radius and a much lower temperature. This is not possible. A 2.0 solar mass main sequence star should have about 1.75 times the sun's radius, and be a hot white star with a temperature of over 8500 K. Sirius is an example of a 2 solar mass main sequence star.
For a 2 solar mass star to be orange-red like that (3000-3500 K) it would have to be a red giant, and would be so big that it would swallow its companion, and possibly the inner binary planet.
Also, the moons will be unstable; the two planets in the binary will be tidally locked to each other. Therefore, their rotational. periods will be equal to Molybdenoria's orbital period. Aurus is closer in than Molybdenoria, and so will have a shorter orbital period, and therefore have a shorter orbital period than its parent's rotational period. The same is true for Lunis. An object with an orbit faster than its parent's rotation will spiral in and collide with its parent due to tidal effects.
