Description


We used the High-Energy Transmission Grating Spectrometer on board the Chandra X-Ray Observatory to perform two observations, separated by 3 weeks, of the Orion Trapezium region. The zeroth-order images on the Advanced CCD Imaging Spectrometer provide spatial resolution of 0.5" and moderate energy resolution. Within a 160"x140" region around the Orion Trapezium, we resolve 111 X-ray sources with luminosities between 7x10^28^ and 2x10^32^ergs/s. We do not detect any diffuse emission. All but six sources are identified.
