Low-mass evolution from HE ignition to beyond the horizontal branch
The evolution of an 0.6 M/sub solar mass/ stellar model during core helium burning is presented. Following the off-center ignition of helium in the core flash, the star remains on the red giant branch for > 10/sup 6/ years, undergoing twelve additional flashes. After leaving the giant branch, the star evolves on the horizontal branch for 8.15 x 10/sup 7/ years before returning to the giant branch and undergoing strong helium-shell flashes. The implications for horizontal branch and RR Lyrae stars are discussed.
