Abstract
We have identified a small number of faint, red stars in optical and infrared frames taken near the center of the Pleiades cluster. The sampled masses range from 0.25 to 0.04 M<SUB>sun</SUB>. The Pleiades mass function in linear units is consistent with a M<SUP>-1</SUP> power law or with a flat dependence in logarithmic mass units. This dependence is consistent with studies of other young open clusters and suggests that massive brown dwarfs and low-mass stars do not contribute significantly to the dark matter.
