The existence of circumstellar disks around magnetically active M dwarfs in nearby clusters of known age will be investigated, with the goal of defining the relation between age, disk properties, and the evolution of magnetic activity. Early (M0-M1) and late (M4-M5) type stars will be included, to determine if the disks change as a function of mass, in accord with the activity. A further investigation of the redistribution of luminosity into the far-IR in active field stars, as compared to inactive ones, will also be carried out on both early and late type stars. Such redistribution is expected if magnetic activity in M dwarfs is similar to that seen on the Sun. The competing effects of circumstellar disk emission and luminosity redistribution can then be compared in stars of different age and mass. ISO provides the only opportunity to obtain the observations necessary to carry out this program, as the far-IR data required cannot be obtained from the ground, and the IRAS database does not contain the required targets, nor is it sensitive enough to accomplish the goals.
