A question for all you smarter-than-me folks out there
Is there simplified formula or algorithm for coming up with the characteristics of a star based on it's classification (O B A F G K M) and it's mass?
For example, given a class B4 star, with a solar mass of 1.44, can one determine it's solar radius and luminosity?
I'm aware of the concept that luminosity is proportional to mass (L ~ M^3.5) but that only applies to main sequence stars. Rather, the M^3.5 seems to only apply to main sequence stars (Class V).
