The process in which hydrogen atoms collide and fuse with each other to form helium in the sun's core is called
radiation
convection
nuclear fusion
conduction
A very large star of high luminosity and low surface temperature. They are the phase of a star after no hydrogen is left to burn and only helium remains.

red giant
blue supergiant
main sequence star
The sun will end its "life " as this type of star, when a star has used up its helium and its outer layers escape into space, leaving behind a hot, dense core that contracts
