Red giant star formation
Most of the stars in the universe are main sequence stars — those that convert hydrogen into helium in their cores via nuclear fusion.
Over the course of their "normal" lives, the outward pressure of fusion inside main sequence stars balances out the inward pressure of gravity.
Once the core fusion stops, however, gravity takes over and begins compressing the star.
"This raises the internal temperature of the star and ignites a shell of hydrogen burning around the inert core," Swinburne University of Technology in Australia wrote in a stellar evolution explainer.
"Meanwhile, the helium core continues to contract and incr
