Upper Mass Limits for Hydrogen-Rich Planetary Nebula Nuclei
Published online by Cambridge University Press: 25 April 2016
Abstract
We have discovered a radiation levitation mechanism which, under certain circumstances, can remove the last vestiges of hydrogen-rich material from an incipient planetary nebula nucleus if its mass exceeds a critical value of about 0.85M⊙. This process may be responsible for the production of helium-rich planetary nuclei, and their progeny the DB white dwarfs.
