What happens to a star after it has become a red giant?

WebA: Laura, A Red Giant star is formed when a star like our sun, or one larger, runs out of its hydrogen fuel. Inside a star, hydrogen atoms are combined together to form helium atoms. This process creates the energy that the star needs to resist the force of gravity that is trying to crush the star together, and also causes the star to light up. WebThe red line is the initial or zero-age main sequence. The numbers along the tracks indicate the time, in years, required for each star to reach those points in their evolution after leaving the main sequence.

Astronomers estimate that this zone will expand past the Earth's orbit in about a billion years. WebLow-mass stars all have long lifetimes on the main sequence and go through the same basic life stages: 1) main sequence 2) red giant with hydrogen shell fusion 3) helium flash 4) white dwarf They differ in details like the depth of their convective zone and their rotation rates. These two factors in thurn affect how active the stars are.

WebA number of factors can contribute to the loss of mass in giant stars, including: Gravitational attraction of a binary companion; Coronal mass ejection-type events; Ascension to red giant or red supergiant status; Solar wind.
