Making the Main Sequence

Main Sequence

A Hertzsprung-Russell diagram or H-R diagram. This plot of a star's temperature, and intrinsic brightness, shows where in its lifespan a particular star is. The solid line (main sequence) is where stars spend the majority of their lifetimes.

H-R Diagram Schematic

The region of the temperature luminosity plot where most stars reside is called the main sequence. Most stars are there, because as we will discover, that is where they spend the majority of their lives. Stars that are not on the main sequence are called giants or dwarfs, and we will see in coming chapters how stars leave the main sequence and end up in the far corners of the temperature-luminosity plot.
