Properties of the Young Stellar Object N 160 A-IR

Abstract

We present near- and mid-infrared images of the young stellar object N 160 A-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 H ii region N 160 A. 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 - 45 mu m) where most of the dust features are located. N 160 A-IR shows the unidentified infrared bands (UIBs) and silicate absorption on a steeply rising continuum plus fine structure lines from the H ii region. A radiative transfer model for the YSO with a luminosity of 1.4*10(6) L_⊙ being deeply embedded (A_V=60 mag) in its parental cloud reproduces the observations. The mass of the model cloud is 50,000 M_⊙ consistent with other estimates. Based on observations with ISO, an ESA project with instruments funded by ESA Member States (especially the PI countries: France, Germany, the Netherlands and the United Kingdom) with the participation of ISAS and NASA.
