我们报道了OMC-2和OMC-3的Chandra观测的X射线结果。约100 kS的深度曝光探测到ACIS阵列视场中的约400个X射线源，提供了恒星形成区域中最大的X射线星表之一。对震源检测、时间可变性和能谱进行了相干研究。我们根据近红外对应的J、H和K波段的颜色将X射线源分为I类、II类和III+MS类，并讨论了这些演化阶段的X射线性质(温度、吸收和时间变异性)。
We report X-ray results of the Chandra observation of OMC-2 and OMC-3. A deep exposure of ~100 ks detects ~400 X-ray sources in the field of view of the ACIS array, providing one of the largest X-ray catalogs in a star-forming region. Coherent studies of the source detection, time variability, and energy spectra are performed. We classify the X-ray sources into Class I, Class II, and Class III+MS based on the J-, H-, and K-band colors of their near-infrared counterparts and discuss the X-ray properties (temperature, absorption, and time variability) along these evolutionary phases.
