Scientific paper

One of the most spectacular star-forming regions in Orion is the young infrared cluster in NGC 2071. Its importance derives from the presence of several massive protostars in a dense central subgroup known as NGC 2071-IR, which are some of the closest such objects known. A recent XMM-Newton observation resulted in the surprising detection of hard X-ray emission accompanied by a strong fluorescent Fe I line from the central group of massive protostars. The emission is likely associated with the massive embedded protostar IRS-1, which drives a powerful bipolar outflow. We propose a follow-up Chandra observation that will provide the high angular resolution needed to reliably identify IR counterparts in the crowded cluster core and search for signatures of shock-related emission.
