Dynamical Instability of the Envelopes of Red Supergiants and the Origin of Planetary Nebulae
Published online by Cambridge University Press: 14 August 2015
Abstract
Deep convective envelopes of the red supergiants with masses smaller than 4 M⊙ are found to be dynamically unstable for the luminosities in the range of 4 × 103–5 × 104L⊙. The total energy of the envelopes is positive when the recombination energy of the ionized hydrogen and helium is taken into account, and is sufficient to expel a typical envelope up to infinite distance at a speed of 30 km/sec. We suggest that planetary nebulae are formed in this way.
