Calculating the mass, diameter, temperature, and luminosity of a star for a habitable zone (HZ) centered at 93 AU presents significant challenges, as it requires an exceptionally luminous star that emits high levels of UV radiation, which can destabilize chemical bonds. The discussion highlights the need to consider the star's lifespan and the intensity of incoming light, which must be similar to Earth's for human habitability. A lower A-class star may be considered, but its short lifespan complicates the scenario, suggesting an F-class star might be more suitable despite concerns about luminosity. The orbital period of 39.36 years for a planet in the HZ and the stability of moons in co-orbit are also critical factors that need to be addressed. Ultimately, achieving a scientifically plausible setup may require sacrificing certain parameters to ensure compatibility with known astrophysical principles.

Wow! Thanks for that, much more than I expected, and certainly looks like it'll be enough to set up the system according to plausible principles :)

I'll get into it in more detail tomorrow (it's a bit late in the UK where I am to be trying to get my head round it all).

When the books get published, I'm going to have to add an acknowledgments section! :)
