NEBULAR KINEMATICS OF PLANETARY NEBULAE AS TESTS OF POSSIBLE DIFFERENCES OF DISTRIBUTION OF PERMITTED AND FORBIDDEN EMISSION LINES
In gaseous nebulae the abundances of heavy elements derived from recombination lines are systematically higher than those derived from collisionally excited lines. The possible explanations to obtain compatible solutions are: either to attribute the difference to the presence of temperature inhomoge...
