Which star is brighter an f2 or an f0s star and why?

Answer 1

An F0 star is brighter than an F2 star. The classification of stars using the Harvard spectral classification system indicates that F0 stars have a higher temperature and luminosity compared to F2 stars, which are cooler and less luminous. The brightness of a star is largely determined by its temperature and size, with F0 stars being more massive and capable of producing more energy than their F2 counterparts.
