Three-Dimensional Adaptive Mesh Refinement Simulations of Point-Symmetric Nebulae
Previous analytical and numerical work shows that the generalized interacting
stellar winds model can explain the observed bipolar shapes of planetary
nebulae very well. However, many circumstellar nebulae have a multipolar or
point-symmetric shape. With two-dimensional calculations, Icke showed that
these seemingly enigmatic forms can be easily reproduced by a two-wind model in
which the confining disk is warped, as is expected to occur in irradiated
disks. In this contribution we present the extension to fully three-dimensional
adaptive mesh refinement simulations of such an interaction.Comment: 4 pages, 2 figures, to appear in "Asymmetrical Planetary Nebulae III"
