As a star's size increases, its luminosity generally **increases**. This is because larger stars have more surface area from which to emit light and heat.
As a star's temperature **increases**, its luminosity also **increases**. According to the Stefan-Boltzmann law, the luminosity of a star is proportional to the fourth power of its temperature. Thus, even a small increase in temperature can lead to a significant increase in luminosity.
