This happens when a main sequence star uses up all of its fuel and swells. Next stage: Red Giant.
Its temperature. Red stars are stars with a cooler temperature, typically because the outer layers are much farther from the center of the star, where the fusion actually occurs. Most "main sequence stars" like the Sun are destined to enter a red giant phase as they exhaust their supply of hydrogen, and they begin to expand as reactions occur around an inert helium core.
A star is "born" when the compression of the surrounding hydrogen and other gases has compressed the core of a protostar to about 10 millionoK when nuclear fusion occurs. The star is now on the main sequence and is classified as a star

The dense gaseous nebulae where star formation occurs are called "stellar nurseries." A star may begin to coalesce due to gravitational disturbances that compress the gases of the nebula.
