Determining luminosity

I'm pretty much new here although I've been working on SRc Alf Ori for quite some time. Specifically delving around its Luminosity/Mass Loss relationship as coined by new researches about stars in the RSB [e.g. Beasor (2020)]. Anyways, I'm entailed to utilize the light curve generated by Vstar and may I ask if there's an available code/program that does 'sort of' converts it onto luminosity?

Looking forward for your responses (and may as well be suggestions/recommendations).

Given your background , this

Given your background , this should get you there:

Surface area is in square meters and temperatue is in degrees Kelvin.

The article also relates luminosity to magnitude.

Skip the part about radio Luminosity (or not, if you like Janskys).

Mag to Luminosity

If you can specify the equation, the latest VStar release has a plugin that can be used to "transform" the magnitude of observations.
