variability and mass loss are the most characteristic features of th majority of the stars on the asymptotic giant branch (agb). the spectrometers on board of iso are unique tools to cover both the r^ant molecular bands probing the atmospheric properties and the dust emission observable at longer wavelengths. the pi of this proposal was asked by christoffel waelkens on behalf of iso otac to submit a discretionary time proposal on one hand covering neclected groups of agb-varables and on the other hand adding complementing spectroscopic data on well studied important groups of agb-stars. emphasis was also put on peculiar and transition objects maybe carring the keys for understanding the evolution of stars on and from the agb. to this end sws and lws observations of a large number of stars is planned. the data will be public domain one month after the pi will receive the final data products. on the www-page http://www.ast.univie.ac.at/virgulfzi/agb/agbwww.html a link will point to a page making the data available for downloading. the groups of objects forseen for observation are oxygen- or carbon-rich agb-variables of type mira, semiregular (sra, srb) or irregular (lb), or are peculiar or transition objects (detached shells, bipolar ouflows, post-agb, young pn).

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.
