X-Ray Properties of Young Stellar Objects in OMC-2 and OMC-3 from the Chandra X-Ray Observatory
Abstract
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.
