The kinematical behavior of Galactic PNe with [WC] central star

TL;DR

This study analyzes the kinematic properties of galactic planetary nebulae with [WC] central stars using high-resolution spectroscopy to determine velocities and peculiar motions, providing insights into their dynamics.

Contribution

It provides the first comprehensive kinematic analysis of [WC] planetary nebulae with precise velocity measurements and derived peculiar velocities.

Findings

[WC] PNe exhibit diverse kinematic behaviors.

Most [WC] PNe have velocities consistent with galactic disk population.

The peculiar velocities suggest varied evolutionary histories.

Abstract

High resolution spectroscopic data of a large sample of galactic planetary nebulae with [WC] central stars ([WC]PNe) are analyzed to determine their kinematical behavior. Their heliocentric velocities have been determined with a precision better than a few km/s. Distances obtained from the literature are used to derive the peculiar velocities of the objects.
