Abstract

Eggleton et al . (Reports, 8 December 2006, p. 1580) reported on a deep-mixing mechanism in low-mass stars caused by a Rayleigh-Taylor instability that destroys all of the helium isotope 3 He produced during the star's lifetime. Observations of 3 He in planetary nebulae, however, indicate that some stars produce prodigious amounts of 3 He. This is inconsistent with the claim that all low-mass stars should destroy 3 He.
