PACS spectroscopy of OH/IR stars
R. Lombaert, B. L. de Vries, L. Decin +5
Observations of high-excitation molecular emission lines can greatly increase our understanding of AGB winds, as they trace the innermost regions of the circumstellar envelope. The…

Detection of the 69 μm band of crystalline forsterite in the Herschel MESS-program
B. L. de Vries, D. Klotz, R. Lombaert +13
In this article we present the detection of the 69 μm band of the crystalline olivine forsterite within the MESS key program of Herschel. We determine the temperature of the forste…

Determining the forsterite abundance of the dust around AGB stars
B. L. de Vries, M. Min, L. B. F. M. Waters +2
We present a diagnostic tool to determine the forsterite abundance of the dust ejected by AGB stars. Our method is based on a comparison between the observed strength of spectral b…
