Description we propose to study the mass loss phenomenon during the final phases of the asymptotic giant branch (agb) evolution. to resolve the mass loss history over the longest possible look-back times we need to map the cold (20-30 k) and faint outer parts of the dust shells with the best possible sensitivity. this cannot be done from the ground; the iras data base and the kuiper airborne observatory do not have sufficient sensitivity. for our purposes isophot-c is the instrument of choice. we will make very deep images at 90 and 160 microns of the extended dust shells around obscured agb stars and young post-agb stars using oversampled raster maps (aot pht32). for sources at a typical distance of 0.5 kpc, the spatial resolution and sensitivity will be sufficient to study in detail the history of the agb mass loss with a time resolution of 3,000 yr and a look-back time of 1e5 yr (virgul1-2 thermal pulse cycles). in addition, the integrated dust distributions of the shells will provide much improved limits on their dust masses, a property which is much debated and poorly known. finally, the square maps will enable us to observe the dust shell morphology on the largest scales.

Mission Description The Infrared Space Observatory (ISO) was the world's 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.
