Description ====================================================================== we have discovered narrow emission lines in the sws full grating spectra of a number of oxygen-rich mira variables. these lines are only detected in stars that also show the 13um dust feature in their spectra. this dust feature has been attributed to some form of aluminum oxide. since shocks in mira atmospheres are supposed to play an important role in the dust formation close to the star, where aluminum oxide is supposed to freeze out, the 13um feature and the emission lines may be related to the presence of shocks in the extended mira atmosphere. in this proposal, we want to obtain high resolution sws spectra of a sample of bright mira variables that show the 13um feature with the aim of (1) detecting these emission lines in the spectrum of more miras (2) confirming the correlation between the presence of the 13um feature and these narrow emission lines. obsid : tdejong propid : agbstar2

Mission Description The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
