Abstract:
-
We present Infrared Space Observatory (ISO) Short Wavelength Spectrometer
(SWS) observations for 16 Wolf-Rayet ([WR]) planetary nebulae (PNe) in
the range from 2.4 to 16.5 μm with the aim of analyzing the dust
features present in this group of objects. We have found that Policyclic
Aromatic Hydrocarbon (PAH) molecular bands are present in most of the observed
[WR] planetary nebulae with clear exception for K 2-16 among late type
[WC] stars.
