    ISO-SWS Spectra of AGB Stars

    In this contribution, we present a few highlights of the guaranteed time program to observe AGB stars with differing chemical compositions and mass loss rates using ISO1 SWS. We briefly discuss C2H2 absorption in...

    Circumstellar Silicate Mineralogy

    This paper reviews spectra obtained with the SWS on board of ISO of dust shells around O-rich objects. These spectra reveal the presence of many new emission features between 10 and 45 µm. These bands are gene...

    Spectroscopic Study of Carbon Stars with the ISO-SWS

    We have observed ten carbon stars with different mass-loss rates using the Short Wavelength Spectrometer (SWS) on board ISO. We found that not only the spectral energy distribution and the dust features, but t...

    Observations of high co rotational lines in post-AGBs and PN

    We present a preliminary interpretation of high CO rotational line data obtained from KAO. The possibility of either a PDR or a shock model is considered in order to explain the observations.

    The onset of axial symmetry in protoplanetary nebulae

    We have obtained resolved IR images, at wavelengths from 1.2µm to 12.5µm, of a small sample of protoplanetary nebulae. The results suggest that all PPNe are axially, not spherically, symmetric, that spherical sym...
