Weak and Extended H2 Emission in NGC 6369
Gerardo Ramos-Larios, Martin A. Guerrero, Roberto Vazquez +1
NGC 6369 is a double-shell PN with a filamentary outer shell or envelope and faint bipolar extensions. We have used ground- and space-based narrowband optical and near-IR images, b…
The Structure of the Planetary Nebula NGC 2371 in the Visible and Mid-Infrared
G. Ramos-Larios, J. P. Phillips
We investigate the structure of the planetary nebula (PN) NGC 2371 using [OIII]-5007 imaging taken with the Jacobus Kapteyn 1.0 m telescope, and [NII]-6584, [OIII]-5007 and Ha resu…
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…
