dc.descriptionWe have investigated the possibility that radiation pressure might trigger planetary nebula (PN) ejection during helium-shell flashes in asymptotic- giant-branch (AGB) stars. We find that the outward flux at the base of the hydrogen envelope during a flash will reach the Eddington limit when the envelope mass falls below a critical value that depends on the core mass and composition. These results may help to explain the helium-burning PN nuclei found in the Magellanic Clouds.
