It's the actual radius of the star, which increases as the star grows brighter during its main-sequence lifetime.

It's not used anywhere in the star generation sequence itself, but it can be of interest to some users. I use it to figure out how large the star appears in the sky from each planet and moon, as an aid to setting scenes. In a Traveller campaign it would be important to interstellar travel, because the J drive in the Traveller setting only works if you are farther from the star than 100 times its diameter (and from each planet that 100 times its diameter).
