The ISO spectrum of the young star HD 142527.

Abstract (from CDS):

We present a detailed analysis of SWS (2.35-45µm) and LWS (43-200µm) spectra obtained with the Infrared Space Observatory (ISO) (Kessler et al., 1996A&A...315L..27K) of the dusty circumstellar disk surrounding the isolated young Fe star HD 142527. Two dust populations can be clearly discriminated: a warm component which is dominated by very strong silicate emission at 10µm, but in which C-rich dust is observable as well, and a cool component, of which the spectrum is dominated by O-rich dust features (C-rich dust not cause obvious features in the far infrared). Besides silicates, crystalline water-ice and hydrous silicates - which are also found in interplanetary dust particles - are present in the cold circumstellar environment. The ISO spectrum of HD 142527 differs markedly from that of HD 100546 (Malfait et al., 1998A&A...332L..25M) and other objects in a similar evolutionary stage and with a similar broad-band energy distribution. No clear correlations between the spectral dust signatures and the stellar parameters can be found at the present stage.
