What can we learn about the kinematics of bright extragalactic planetary nebulae
M. G. Richer, S. -H. Baez, J. A. Lopez +2
We present high resolution spectroscopy in the [\ion{O}{3}]5007 and H lines of bright planetary nebulae in the Milky Way bulge and the dwarf galaxies M32, Fornax, Sagittarius…
The Acceleration of the Nebular Shells in Planetary Nebulae in the Milky Way Bulge
Michael G. Richer, Jose Alberto Lopez, Margarita Pereyra +3
We present a systematic study of line widths in the [\ion{O}{3}]5007 and H lines for a sample of 86 planetary nebulae in the Milky Way bulge based upon spectroscopy obtained…
Revised Diagnostic Diagrams for Planetary Nebulae
H. Riesgo, J. A. López
Diagnostic diagrams of electron density - excitation for a sample of 613 planetary nebulae are presented. The present extensive sample allows the definition of new statistical limi…
The kinematics of the large western knot in the halo of the young planetary nebula NGC 6543
Deborah L. Mitchell, M. Bryce, J. Meaburn +5
A detailed analysis is presented of the dominant ionised knot in the halo of the planetary nebula NGC 6543. Observations were made at high spectral and spatial resolution of the [O…
