Descripción
The kinematics of Planetary Nebulae are analyzed in terms of the
solutions to the equations of hydrodynamic equilibrium developed by J.
Canto. We apply our analysis to the Planetary Nebulae NGC 6905 and NGC
6537. A detailed spectroscopic study of these objects reveals the
existence of high nuclear velocities, together with complex kinematic
structures and unusual emission line intensities. Shock ionization
clearly plays a key role in these nebulae. Remarkably good agreement is
obtained when comparing the synthetic maps and spectra resulting from
the shock solutions with the observational data.
