Optical and Mid-Infrared Observations of the Planetary Nebula NGC 6781
J. P. Phillips, Gerardo Ramos-Larios, Martin A. Guerrero
Although the planetary nebula NGC 6781 appears to possess an elliptical morphology, its kinematic and emission characteristics are in many ways unusual, and it is possible that it…
Mid and Far Infrared Photometry of Galactic Planetary Nebulae with the AKARI All Sky Survey
J. P. Phillips, R. A. Marquez-Lugo
We provide mid- and far-infrared photometry of 857 Galactic planetary nebulae (PNe) using data derived from the AKARI All-Sky Survey. These include fluxes at 9 and 18 μm obtained w…
Mid-Infrared Observations of Planetary Nebulae detected in the GLIMPSE 3D Survey
J. A. Quino-Mendoza, J. P. Phillips, G. Ramos-Larios
We present mapping, profiles and photometry for 24 planetary nebulae (PNe) detected in the GLIMPSE 3D mid-infrared (MIR) survey of the Galactic plane. The PNe show many of the prop…
The Halo and Rings of the Planetary Nebula NGC 40 in the Mid-Infrared
G. Ramos-Larios, J. P. Phillips, L. C. Cuesta
We present imaging and spectroscopy of NGC 40 acquired using the Spitzer Space Telescope (Spitzer), and the Infrared Space observatory (ISO). These are used to investigate the natu…
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…
