Star system polymorphism

Star system polymorphism describes the presence of stars in a single system all being in different stages to their evolution. The characteristics of stars are all different in a single system, thus they are polymorphic. Some are older, more massive, cooler, dimmer, smaller, etc. This is in direct opposition to the claim that the star systems are uniform, and they are suppose to resemble or match characteristics of the solar system we inhabit.
