How does mass determine a stars evolution?

A star's mass is the primary factor that dictates its evolutionary path. More massive stars burn their nuclear fuel at a much faster rate, leading to shorter lifespans and more dramatic end-of-life events, such as supernovae. In contrast, less massive stars, like red dwarfs, burn fuel slowly and can last for billions of years, often ending their lives as white dwarfs. Thus, the mass of a star determines not only its lifespan but also its eventual fate in the universe.
