The Formation of Planetary NebulaeA hydrodynamic model of a star consisting of a helium shell and a hydrogen-rich shell overlying a hard core is proposed in order to find out what causes the ejection of stellar mass with low velocities that form planetary nebulae. Observations indicate that a planetary nebula is composed of hydrogen-rich material, while the remaining remnant of the star is of helium or heavier material.
