WebThe track for a 1-solar-mass star shows that the Sun is still in the main-sequence phase of evolution, since it is only about 4.5 billion years old. It will be billions of years before the Sun begins its own “climb” away from the main sequence—the expansion of its outer layers that will make it a red giant. Webany of the very short-lived proto-stellar evolution; stars begin on the main sequence where they spend most of their lives. It is at this time in a star's life that it is in hydrostatic equilibrium and is turning hydrogen into helium and energy in its core in a process known as thermonuclear fusion. The star
