Total radiation flux from a star

I'm looking around the net to find good resources on how to compute total radiation flux from a given star at a given orbiting distance.

Ideally I'd like to get not just the $W/m^2$ of the star, but also the expected high-energy particles, EM, thermal, solar wind pressure.. well, the works.

Everywhere I looked they seem to compute these values for our Sun and at 1AU, then I'm left to wonder how this relates to stellar mass, composition type, luminosity, distances, etc.

In the end, I'm trying to quantify a sort of habitability range around a given star. Much in the way of saying: well, given this blue-hypergiant you could get close to about $40$ $AU$ before you get toasted in your puny spacecraft. Or, habitable planets could exist between $100$ AU and $120$ AU.etc..

I would have thought this would have been more common around sf projects, but radiation seems to go unnoticed in most sf themes.

Stars are (ironically) pretty good approximations to black bodies, so if you know their surface temperature and surface area you can calculate the radiation emitted using the Stefan-Boltzmann law.

This only applies to electromagnetic radiation. I don't know how you'd calculate the intensity of the stellar wind. However whether you'd get toasted or not is mainly down to the EM radiation.
