Envelope ejection leading to a planetary nebula has been recently shown to occur as the terminal point of the Mira stage. The ejection is due to a diverging pulsational instability, not to a dynamical one. It is found that in this case (and for Population I, mixing length = 1 pressure scale height) the upper mass limit for formation of planetary nebulae is at least 6 solar masses. It thus follows that the lower mass limit for realization of carbon detonation model configurations is also at least 6 solar masses.
