isocam will be used to survey selected regions of the small and large magellanic clouds in order to detect evolved stars with mass loss. these stars will be primarily identified by their observed infrared colors. the sources detected will also be compared with ground-based spectroscopic and near-ir surveys of the same fields. the populations in the two galaxies will be compared to see whether the sizes of the detected excesses are proportional to metal abundance, which would imply roughly constant mass-loss rates for similar stars in the two galaxies. if the mass loss rates are not similar, or source densities are very different the data set should be large enough to look for other effects that may explain the differences, for example effects related to the different c to m star ratios in the lmc and smc.

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.
