Descripción
We present new results of a program aimed at studying the physical
properties, origin and evolution of those phenomena which go under the
somewhat generic definition of "low-ionization, small-scale structures
in PNe". We have obtained morphological and kinematical data for 10 PNe,
finding low-ionization structures with very different properties
relative to each other, in terms of expansion velocities, shapes, sizes
and locations relatively to the main nebular components. It is clear
that several physical processes have to be considered in order to
account for the formation and evolution of the different structures
observed. We present here some results that are illustrative of our work
- on IC 4593, NGC 3918, K 1-2, Wray 17-1, NGC 6337, He 2-186 and K 4-47
- and some of the questions that we try to address.
