Abstract (from CDS):

We present near infrared JHK imaging of the Small Magellanic Cloud compact HII region N81 using the ISAAC camera at the ESO Very Large Telescope (Antu). Our analysis of the stellar environment of this young massive star region reveals the presence of three new stellar populations in the surrounding field which are mainly composed of low mass stars. The main population is best fitted by evolutionary models for ∼2M stars with an age of 1Gyr. We argue that these populations are not physically associated with the HII region N81. Instead they are the result of a number of low mass star forming events through the depth of the SMC south of its Shapley's wing. The populations can rather easily be probed due to the low interstellar extinction in that direction.
