Abstract

We have performed a morpho-kinematic analysis of the planetary nebula NGC 6058 based on direct imaging, high dispersion spectroscopy and the modeling tool SHAPE ver.3.5. NGC 6058 can be described as a high-excitation multipolar PN that consists of four ellipsoids oriented in different directions with similar inclinations with respect to the plane of the sky. We have also found point symmetric knots that trace the edges of the largest ellipsoid. A precesing collimated outflow might be a reasonable origin for the present structure of this nebula. We propose that NGC 6058 is probably an advanced stage of a ``starfish'' PN.
