The [S ii] Spectral Images of the Planetary Nebula NGC 7009. II. Major Axis

We derived position–velocity density distribution diagrams along the major (PA = 77°) axis of the elliptical planetary nebula NGC 7009 with the Keck HIRES [S ii ] 6716/6731 Å doublet spectral images. The average densities of the main shell and knots of NGC 7009 derived from the [S ii ] 6716/6731 Å f...
