High-velocity bipolar mass flow in the planetary nebula NGC 2392.
Abstract
Detailed spectroscopic observations of a high-velocity component in the velocity field of the "Eskimo" nebula, NGC 2392, are presented. It is interpreted as a jetlike multiknot bipolar mass flow with a velocity of nearly 200 km s-1 and a small angle of collimation less than 10°. Electron density, mass, kinetic energy, and power are estimated.
