Abstract (from CDS):

We present near- and mid-infrared images of the young stellar object N160A-IR in the Large Magellanic Cloud (LMC). For the first time, the YSO is seen in the NIR as a compact point source in the north-western part of the HII region N160A. Furthermore, we present ISO-SWS spectra pointed on the YSO. The spectra cover the full wavelength range of SWS on board of ISO (2.5-45µm) where most of the dust features are located. N160A-IR shows the unidentified infrared bands (UIBs) and silicate absorption on a steeply rising continuum plus fine structure lines from the HII region. A radiative transfer model for the YSO with a luminosity of 1.4x106L☉ being deeply embedded (AV=60mag) in its parental cloud reproduces the observations. The mass of the model cloud is 50,000M☉ consistent with other estimates.
