... The total energy production rate falls from its red giant phase peak. This reduces the star’s luminosity and decreases the star’s radius, making its surface hotter. In the H-R diagram, the star goes down and to the left. All low-mass stars fuse helium into carbon at nearly the same rate they have ...
