Description
Highly collimated bipolar outflows have been detected in the planetary
nebula NGC 6572 via ground-based optical imagery and high-resolution
long-slit spectroscopy. Kinematics and morphology together provide
strong evidence of a direct interaction between the collimated outflows
and the nebular elliptical shell, creating a double point-symmetric
structure. As a consequence of this interaction, the elliptical shell
has been broken up, and in this process parts of the shell have been
accelerated, while the collimated outflow has been slowed down and/or
deflected. These results strengthen the notion that collimated outflows
are common in planetary nebulae and may play an important role in
shaping the nebular shells. In addition, our kinematic data give a solid
confirmation of previous estimates used to derive the distance to this
nebula with the parallax expansion method.
