As a star exhausts its hydrogen fuel in the core, nuclear fusion ceases, causing the core to contract under gravity. This contraction increases temperature and pressure, triggering helium fusion and causing the outer layers to expand and cool, transforming the star into a red giant. The increased luminosity and size result from the energy produced in the shell surrounding the core, leading to the characteristic red hue of the giant phase.

What star is a red super giant?
Its a very large star that is coming to the end of its life. A star will expand as the forces change within, caused by changes in the fuel that it uses. they are very large and red, indicating a lower temperature. They are also not very dense, so sometimes their mass is relatively low compared with their size.
