Discovery of collimated bipolar outflows in the planetary nebula Th 2-A
  We present a comprehensive set of spatially resolved, integral field
spectroscopic mapping of the Wolf-Rayet planetary nebula Th 2-A, obtained using
the Wide Field Spectrograph on the Australian National University 2.3-m
telescope. Velocity-resolved H$\alpha$ channel maps with a resolution of 20 km
s$^{-1}$ allow us to identify different kinematic components within the nebula.
This information is used to develop a three-dimensional morpho-kinematic model
of the nebula using the interactive kinematic modeling tool SHAPE. These
results suggest that Th 2-A has a thick toroidal shell with an expansion
velocity of 40 $\pm$ 10 km s$^{-1}$, and a thin prolate ellipsoid with
collimated bipolar outflows toward its axis reaching velocities in the range of
70-110 km s$^{-1}$, with respect to the central star. The relationship between
its morpho-kinematic structure and peculiar [WO]-type stellar characteristics
deserves further investigation.
