Abstract

We have performed integral field spectroscopy of the planetary nebulae Hen 3-1333 (PNG332.9-09.9) and Hen 2-113 (PNG321.0+03.9), which are unusual in exhibiting dualdust chemistry and multipolar lobes but also ionized by late-type [WC 10] central stars. The spatially resolved velocity distributions of the Hα emission line were used to determine their primary orientations. The integrated Hα emission profiles indicate that Hen 3-1333 and Hen 2-113 expand with velocities of ~32 and 23 km s-1, respectively. The Hubble Space Telescope observations suggest that these planetary nebulae have two pairs of tenuous lobes extending upwardly from their bright compact cores. From three-dimensional geometric models, the primary lobes of Hen 3-1333 and Hen 2-113 were found to have inclination angles of about -30° and 40° relative to the line of sight, and position angles of -15° and 65° measured east of north in the equatorial coordinate system, respectively.
