Quizplus · Accepted Answer

The mass of a star primarily determines its location on the main sequence. As a star ages, its location on the main sequence may shift slightly as it consumes its fuel and undergoes changes in temperature and luminosity, but its mass is the most significant factor in determining its position on the main sequence. Stars with higher masses are hotter and more luminous, and therefore occupy the upper left portion of the main sequence, while stars with lower masses are cooler and less luminous, and therefore occupy the lower right portion of the main sequence.
