Star mass/luminosity for a given HZ

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! :)
