We have already used the H—R diagram to follow the evolution of protostars up to the time they reach the main sequence. Once a star has reached the main-sequence stage of its life, it derives its energy almost entirely from the conversion of hydrogen to helium via the process of nuclear fusion in its core see The Sun: A Nuclear Powerhouse. Thus, all stars remain on the main sequence for most of their lives. The left-hand edge of the main-sequence band in the H—R diagram is called the zero-age main sequence see Figure We use the term zero-age to mark the time when a star stops contracting, settles onto the main sequence, and begins to fuse hydrogen in its core. The zero-age main sequence is a continuous line in the H—R diagram that shows where stars of different masses but similar chemical composition can be found when they begin to fuse hydrogen. Since only 0. It does, however, change the chemical composition in its central regions where nuclear reactions occur: hydrogen is gradually depleted, and helium accumulates. This change of composition changes the luminosity, temperature, size, and interior structure of the star. Calculations show that the temperature and density in the inner region slowly increase as helium accumulates in the center of a star.

Stars are some of the fundamental building blocks of the universe. They not only make up galaxies, but many also harbor planetary systems. So, understanding their formation and evolution gives important clues to understanding galaxies and planets. The Sun gives us a first-class example to study, right here in our own solar system. It's only eight light-minutes away, so we don't have to wait long to see features on its surface. Astronomers have a number of satellites studying the Sun, and they've known for a long time about the basics of its life.

Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to times as massive.
