Abstract:
-
We have analyzed Infrared Space Observatory Short Wavelength Spectrometer
(ISO-SWS) observations for 16 Wolf-Rayet ([WR]) planetary nebulae (PNe)
with the aim of identifying the dust features present in this group of
objects. We have found that Polycyclic Aromatic Hydrocarbon (PAH) molecular
bands (which are present in most of the observed [WR] PNe)
are more frequent than crystalline silicate features.
