Spatially resolved kinematic observations of the planetary nebulae Hen 3-1333 and Hen 2-113

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 dual-dust chemistry and multipolar lobes but also ionized by late-type [WC 10] 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 Hen 3-1333 and Hen 2-113 expand with velocities of ~ 32 and 23 km/s, 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${}^{\circ }$ 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.
