Answer:
The temperature needed for hydrodgen burning is 10 million Kelvin, so that's how hot a star must be to be considered as a star. It needs to get so hot, because else it will fail to burn hydrodgen and will become a "failed star": a brown dwarf.
That increased surface area allows more light and energy to be given off. Temperature also affects a star's luminosity. ... As a star gets hotter, the number of nuclear reactions increases. More reactions, more energy.
