WebStar Layers during and after the Main Sequence. Figure 22.2. (a) During the main sequence, a star has a core where fusion takes place and a much larger envelope that is too cold for fusion. (b) When the hydrogen in the core is exhausted (made of helium, not hydrogen), the core is compressed by gravity and heats up. 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.
