we propose to obtain low-resolution spectra of a number of m dwarfs in the range 2.5 - 45 microns. this region is largely unavailable to terrestrial spectrometers and contains many important features which govern the energy output from cool stars. of particular interest is the competition between water and methane as opacity sources and the importance of dust. these observations will allow accurate bolometric luminosities to be derived for m-dwarfs and the measurement of important molecular bands which have not been observed in m dwarfs. spectra of m-dwarfs provide the vital link toward understanding brown dwarfs. these spectra will provide a testbed for model calculations of brown dwarfs around the peak of their energy output.

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.
