Main Sequence


In space and astronautical engineering, the Main Sequence is a continuous and distinctive band of stars that appears on plots of stellar color versus brightness. It represents a stage in the evolution of a star, during which it fuses hydrogen atoms into helium in its core. The Main Sequence includes stars of different masses, from small red dwarfs to massive blue giants, and it is the longest stage in the life cycle of a star, lasting for billions of years. The position of a star on the Main Sequence is determined by its mass, with more massive stars being brighter and hotter than less massive ones. The study of the Main Sequence is important for understanding the formation and evolution of stars, as well as for determining their age and distance from Earth.
