Shaping Planetary Nebulae by Jets

摘要: We conduct 2D axisymmetrical hydrodynamical simulations to investigate the interaction of a collimated fast wind (CFW; wide jets) with spherical AGB wind. The code includes radiative cooling. find that shape planetary nebula (PN) is sensitive exact mass loss history wind, and opening angle CFW. Some typical PN morphologies are obtained, but many other observed seem require more ingredients than what we assume in our present simulations, e.g., equatorial ionization during phase. hot bipolar bubble formed by jets an X-ray source.
