3-D Photoionization Structure and Distances of Planetary Nebulae II. Menzel 1
Hektor Monteiro, Hugo E. Schwarz, Ruth Gruenwald +2
We present the results of a spatio-kinematic study of the planetary nebula Menzel 1 using spectro-photometric mapping and a 3-D photoionization code. We create several 2-D emission…
3-D Photoionization Structure and Distances of Planetary Nebulae I. NGC6369
Hektor Monteiro, Hugo E. Schwarz, Ruth Gruenwald +1
We present the results of mapping the planetary nebula NGC6369 using multiple long slit spectra taken with the CTIO 1.5m telescope. We create two dimensional emission line images f…
Rings in the Haloes of Planetary Nebulae
R. L. M. Corradi, P. Sanchez-Blazquez, G. Mellema +2
We present a search for rings or arcs in the haloes of planetary nebulae (PNe). We discovered such structures in eight PNe, tripling the sample of PNe with known rings. This shows…
