How do stars become red giants

WebMay 7, 2015 · The star has become a red giant. What happens next in the life of a star depends on its initial mass. Whether it was a "massive" star (some 5 or more times the mass of our Sun) or whether it was a "low or medium mass" star (about 0.4 to 3.4 times the mass of our Sun), the next steps after the red giant phase are very, very different. III. The End WebThe star will continue to expand to between 200-800 times the radius of our sun to become a red giant. Stars larger than our sun will increase in size to form a Red Supergiant star. It will expand to about 1500 times the radius of our sun. Both red giants and red supergiants decrease in surface temperature down to around 3500 Kelvin.
