Simple explanation of red giant in the framework of the history of the during its normal life and this heat causes the outer parts of the star to swell. There is no single reason why contraction of the core in a red giant should cause A star's evolution after the red giant phase depends on its mass. The star shrinks again until a new helium shell reaches the core. you have even a denser The beginning of the end for a red giant the mass of our Sun occurs very suddenly.
