The stellar mass spectrum in the young populous cluster NGC 1866.


Abstract (from CDS):

The young populous cluster NGC 1866 in the Large Magellanic Cloud (LMC), which is probably one of the most massive objects formed in the LMC during the last ∼3 Gyr, appears to have an unexpectedly high mass-to-light ratio. From its velocity dispersion Fischer and coworkers find its mass to be (1.35±0.25)x105 M. The luminosity of this cluster is Mv=-8.93±0.13, corresponding to Lv=(3.2±0.4)x105 Lv,☉. This yields M/Lv=0.42±0.09 in solar units. For a cluster of age 0.1 Gyr, such a relatively high mass-to-light ratio requires a mass spectrum with an exponent x=1.72±0.09, or x=1.75±0.09 if mass loss by evolving stars is taken into account.
