ISO-SWS spectrophotometry of galactic Wolf-Rayet stars: preliminary results.
Abstract
ISO-SWS spectra of seven late-type galactic Wolf-Rayet stars are discussed. A high resolution spectrum (2.3-29.6μm, λ/{DELTA}λ=~820-1700) of the WC8 star WR11 (γ^2^ Vel) is shown and its Ne abundance is discussed. Medium resolution spectra (λ/{DELTA}λ=~250-600) of the WC8-9 stars WR48a, WR98a, WR104, WR112 and WR118 show the broad circumstellar heated amorphous carbon dust emission feature and interstellar silicate and hydrocarbon absorption features.
