Radial and expansion velocities of compact planetary nebulae

  • 1. Calgary Univ. (Canada)

Description

Optical spectra centered near 5000 A have been obtained of the compact planetary nebulae M1-6, IC 2149, MI-78, NGC 7027, and CN3-1. The expansion velocities of the ionized outflow and the systemic velocity of each nebula have been determined from the forbidden O III lines at 5007 A and 4958 A. 14 refs
