Models of star formation predict that objects less massive than 0.08MSun become brown dwarfs instead of true hydrogen-fusing stars. Once they have formed, these objects cool because no fusion is occurring to replace the thermal energy lost from their surfaces. How would you expect the properties of brown dwarfs in an older star cluster to compare with those of brown dwarfs in a younger one? Propose an observing program that could test your hypothesis.
