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 tp 16.5 um 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.
