Abstract
We report new estimate for the lower Pleiades mass function across the stellar/substellar boundary. We find that it is well represented by a single power-law dn/dm α m −0.60±0.11 between 0.03M⊙ and 0.45M⊙. Over a larger mass domain, however, the mass function is better fitted by a log-normal distribution. We find that the early dynamical evolution of the cluster appears to have had little e ect on its present mass distribution at an age of 120 Myr. Comparison between the Pleiades mass function and the Galactic disk mass function suggests that apparent differences may be mostly due to unresolved binaries.
