Abstract

We present the first thermal-infrared spectra of an extragalactic Young Stellar Object (YSO), IRAS 05328-6827 in the H II region LHA 120-N 148 in the Large Magellanic Cloud (LMC). The observed and modelled spectral energy distribution reveals a massive YSO, M ~ 20 M_⊙, which is heavily embedded and probably still accreting. The reduced dust content as a consequence of the lower metallicity of the LMC allows a unique view into this object, and together with a high C/O ratio may be responsible for the observed low abundance of water ice and relatively high abundances of methanol and CO₂ ices.
