Stellar process

The Asymptotic Giant Branch

Late in a low- or intermediate-mass star's life, both a hydrogen shell and a helium shell burn around a carbon–oxygen core. Recurring thermal pulses dredge freshly-made elements to the surface and drive heavy mass loss, as the star climbs the asymptotic giant branch toward the ejection of its envelope.
