Abstract:

We have performed integral field spectroscopy of the planetary nebulae Hen3-1333 (PNG332.9$-$09.9) and Hen2-113 (PNG321.0$+$03.9), which are unusual in exhibiting dual-dust chemistry and multipolar lobes but also ionized by late-type [WC10] central stars. The spatially resolved velocity distributions of the H$\alpha$ emission line were used to determine their primary orientations. The integrated H$\alpha$ emission profiles indicate that Hen3-1333 and Hen2-113 expand with velocities of $\sim 32$ and $23$ kms$^{-1}$, 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 Hen3-1333 and Hen2-113 were found to have inclination angles of about $-30^{\circ}$ and $40^{\circ}$ relative to the line of sight, and position angles of $-15^{\circ}$ and $65^{\circ}$ measured east of north in the equatorial coordinate system, respectively.
