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…
The planetary nebula NGC 1360, a test case of magnetic collimation and evolution after the fast wind
M. T. Garcia-Diaz, J. A. López, G. Garcia-Segura +2
The central star of this nebula has an observed intense magnetic field and the fast wind is no longer present, indicating that a back flow process has probably developed. Long-slit…
Large Scale Flows from Orion-South
W. J. Henney, C. R. O'Dell, Luis A. Zapata +3
Multiple optical outflows are known to exist in the vicinity of the active star formation region called Orion-South (Orion-S). We have mapped the velocity of low ionization feature…
Photoevaporation Flows in Blister HII Regions: I. Smooth Ionization Fronts and Application to the Orion Nebula
W. J. Henney, S. J. Arthur, Ma. T. Garcia-Diaz
We present hydrodynamical simulations of the photoevaporation of a cloud with large-scale density gradients, giving rise to an ionized, photoevaporation flow. The flow is found to…
