Infrared Observations of an Extended Planetary Nebula - NGC7293 - the Helix Nebula
Abstract
In this paper it is shown that the broadband fluxes as measured by IRAS in the nebula NGC 7293 are mainly due to atomic line emission; this is probably even true for the long wavelength bands. All the emission in these bands can be explained by line emission, but it is likely that some emission is also due to dust.
