The structures of MASH and MASH II planetary nebulae at mid-infrared wavelengths.
RAMOS-LARIOS G. and PHILLIPS J.P.
Abstract (from CDS):
Finally, it is suggested that differences between the MIR colours of the MASH sources on the one hand, and of less evolved PNe on the other, may arise because of an evolution in the numbers of PAH-carrying grains within the PDRs, and/or variations in the far-ultraviolet (FUV) energy density of the stellar radiation fields. The tendency for fluxes to increase with increasing MIR wavelength probably arises from variations in PAH emission strengths, as well as from the contribution of broader dust continua.
