scientific abstract observations of low mass stars, such as m dwarfs, are vital for models of our galaxy. waters et al. (1987) showed that m stars were under-represented at iras wavelengths. photometry will be performed to establish whether the infrared energy distribution of m dwarfs is of the thermal black-body type, or whether it is dominated by features, either from molecular absorption bands or dust emission. photometry will be performed on a set of m dwarfs, which are not known to have significant mass loss or optical emission features. observation summary pht-p broad band photometry will be performed for all the stars proposed, using p03 with 7 filters and a 99 aperture. the filters selected are; 7.7, 10, 12.8, 16, 25, 60, 100 um. the observations will use the chopper in rectangular mode, with a 120 chop. for gl726, the 100um band is not selected. the integration time selected is 32sec in all cases. the times are estimated using the cookbook.

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.
