Quizplus · Accepted Answer

The mass of a star is the main factor that determines its temperature and luminosity. Higher mass means higher temperature and luminosity, while lower mass means lower temperature and luminosity. This is because higher mass stars have more gravity, which causes greater pressure and denser fusion reactions in their cores, leading to higher temperatures and greater energy output.
