WebThe outward radiation pressure the keeps the star from collapsing is now gone, and gravity causes the star to start to collapse. The collapse of the core causes the temperatures to increase in it and around it. Eventually, the heat of collapse is enough that a shell of hydrogen around the core starts to fuse. WebRed giant stars are of the spectral types M and K and are much smaller than red supergiants and much less massive. When a star has consumed its stock of hydrogen in its core, fusion stops and the star no longer generates an outward pressure to counteract the inward pressure pulling it together.
