The Halos of Planetary Nebulae in the Mid-Infrared: Evidence for Interaction with the Interstellar Medium
G. Ramos-Larios, J. P. Phillips
The motion of planetary nebulae (PNe) through the interstellar medium (ISM) is thought to lead to a variety of observational consequences, including the formation of bright rims; d…
Rings and Halos in the Mid-Infrared: The Planetary Nebulae NGC 7354 and NGC 3242
J. P. Phillips, G. Ramos-Larios, K. -P. Schroeder +1
We present images of the planetary nebulae (PNe) NGC 7354 and NGC 3242 in four mid-infrared (MIR) photometric bands centred at 3.6, 4.5, 5.8 and 8.0 microns; the results of observa…
The Unusual Distributions of Ionized Material and Molecular Hydrogen in NGC 6881: Signposts of Multiple Events of Bipolar Ejection in a Planetary Nebula
G. Ramos-Larios, M. A. Guerrero, L. F. Miranda
The planetary nebula NGC 6881 displays in the optical a quadrupolar morphology consisting of two pairs of highly collimated bipolar lobes aligned along different directions. An add…
The H2 Amazing Life of NGC 6881
G. Ramos-Larios, M. A. Guerrero, L. F. Miranda
The H2 and optical (Ha, [NII]) morphology of NGC 6881 are very different. Here we present a preliminary report of the analysis of new optical (Ha and [NII]) and near-IR (Brg and H2…
