A Mechanism for the Production of Planetary Nebulae
Abstract
C12 stars in the range 1.04 1.55M ⊙ are evolved to simulate the core evolution of the possible precursors of planetary nebulae. The nuclear shell burning in stars above 1.2M ⊙ advances to within about 0.2M ⊙ of the surface, where the intense radiation interacts with the surface matter and causes mass loss. Comparison between our theoretical results and observations suggests that this may be a mechanism by which planetary nebulae are formed.
