Question

Quizplus · Accepted Answer

The mass of a star is the single most important characteristic in determining its evolution because it determines the pressure, temperature, and energy production within the star's core. This, in turn, determines the type of fusion reactions that occur, the duration of each stage of the star's life cycle, and the eventual outcome of the star's evolution. The mass of a star determines its evolution because it determines the internal pressure and temperature of the star, which in turn determines the rate of fusion and the depletion of the star's fuel. A star with a high mass will burn its fuel more rapidly and end its life in a more violent explosion than a star with a lower mass.
