Okie dokie, I searched the web and found L=M ^ 3.5 (luminosity equals mass to the power of 3.5). But, I'm pretty clueless on anything beyond Algebra I. How do I solve for M if I know L? [If the answer can be expressed in Visual Basic syntax, all the better.](adsbygoogle = window.adsbygoogle || []).push({});

I also read several caveats that said the above formula works best for main sequence stars. Does anyone know of better of formula for sub-dwarfs, dwarfs, giants, and super giants? I'm pulling my numbers from a sub-set of the Hipparcos data. So, from absolute magnitude, I can calculate luminosity, but I get stuck after that.

My goal is to calculate solar mass and plug that into Accrete so I can create a fictional but semi-realistic star atlas for hard sci-fi games.

Along a similar line, I've seen some sites that says Accrete is fairly dated as far as solar system modelling goes. Has anyone written a successor to Accrete that is available to the public?
