    The mass-luminosity relationship on your star is badly cockeyed. A star with a mass of 4.29 Sols should have a luminosity of much more than 4.29. As a rule of thumb, I use L = M^3.5.

    For planets with the same insolation, larger stars should have longer years. I'm not even sure if a mass of 4.29 Sols would have a sufficiently long life to evolve complex.. life.

    EDIT:
    For reference, looking at the table at the end of Gillett's World-Building a A0 main-sequence star with a mass of 3.0 Sols has a luminosity of 64 Sols and a B5 main-sequence star with a mass of 5.8 Sols has 810 times the luminosity of the Sun. That brackets the 4.29 Solar masses given for the CWBP2 planet's star. The temperature seems plausible for a star of that mass, but the MS lifetime of such a star would be somewhere between 72 and 470 million years. Life would have to be introduced from elsewhere.
