We present the results of high angular resolution adaptive optics (AO) near-infrared (JHKs ) observations of the deeply embedded massive cluster RCW 38 using NACO on the Very Large Telescope. Narrowband AO observations centered at wavelengths of 1.28 μm, 2.12 μm, and 2.17 μm were also obtained. The area covered by these observations is about 0.5 pc2, centered on the O-star RCW 38 IRS 2. We use the JHKs colors to identify young stars with infrared (IR) excess in this region. Through a detailed… Expand
