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… 
Near-infrared variability in the star-forming region RCW 38
Aims. We want to study the content of young stellar objects in the RCW 38 cluster by means of multi-epoch variability studies. Methods. We performed a three-month near-infrared (NIR) monitoring
Deep near-infrared adaptive-optics observations of a young embedded cluster at the edge of the RCW 41 H II region
Aims. We investigate the star formation activity in a young star forming cluster embedded at the edge of the RCW 41 H ii region. As a complementary goal, we aim to demonstrate the gain provided by
