They correspond to our sun, as their earth is our Earth, except they do not necessarily function identically. Let's look at Arda before the Downfall of Numenor. It was flat, going by the fully-fleshed out Legendarium. Our Earth is not flat. Also, the mechanics actually are what matter, not any correspondence. The mechanics of our sun are what cause the Aurorae, and if the mechanics of the Sun of Arda are not the same, it does not have the same effect. That said, I'm all for Aurorae in the mod, even though they likely would not exist in canon, at least in the appropriate age.
