As a star's size increases, its luminosity increases as a star's temperature increases, its luminosity increases.
luminosity is a calculated unit which means the energy produced by stars or galaxy , it is represent in the form of either joules per second or watts.
It generally depends on the size of the star that the lager sized star more energy it give, more luminous.
Secondly, the temperature of the star, if two same sized stars with different temperature, then higher temperature will be more luminous.
It is otherwise determined the actual measure of the absolute magnitude of the power output of the star.
It can be used to understand the stellar classification of various stars.
It can be used to predict the lifecycle of the star and helps astronomers.
luminosity is much more specific than brightness of the star as it is a mathematical calculation.
