What is the medium mass star definiton?

A medium mass star is typically defined as a star with a mass ranging from about 1.5 to 8 times that of the Sun. These stars undergo nuclear fusion in their cores, primarily converting hydrogen into helium, and they exhibit a range of evolutionary stages, including the main sequence, red giant, and eventually, they may shed their outer layers to form planetary nebulae, leaving behind a white dwarf. This classification helps differentiate them from low mass stars (like red dwarfs) and high mass stars (like massive blue giants).
