Scientific paper

Trumpler 37 is with 3 Myr one of the youngest open clusters in our galaxy. The core of the cluster hosts the Trapezium-like complex HD 206267. Its main component is a young and hot O-star triplet. Twice as distant, this system strongly resembles the Orion Trapezium Cluster. In AO1 we observed Orion twice with the HETGS and found that the high resolution spectrum of the central O-star showed a large number of emission lines which indicated a wide range of temperatures in the wind of up to 11 keV. Furthermore we found a large number of transient X-ray sources in the vicinity, which resemble deeply embedded protostars. In Trumpler 37 we face a similar situation. Two 40 ks exposure with the HETGS allows us to study a similar star formation scenario in IC 1396.
