Abstract (from CDS):

From near-infrared and molecular hydrogen imaging observations, we have discovered that the planetary nebula NGC 6072 has a multipolar structure with a prominent equatorial ring. We have modeled the object by a double bipolar system, each with an equatorial ring and a pair of bipolar lobes. The bipolar axes of the two systems are estimated to be separated by 47°. The existence of such a double bipolar system suggests that the object has undergone separate fast outflow episodes separated by several thousand years.
