To know the stellar population of star forming regions, IR studies are the perfecttool to characterize the evolutionary stage of the objects found. However, it is foundthat at these wavelengths part of the population is lost, because they are very absorbedor because they cease to show infrared properties. Therefore, it is necessary to lookfor a complementary method to relieve the entire population. As with radio-waves,hard X-rays (> 1 keV) pass through clouds of gas and dust without interacting withmatter due to the eective section of the latter. This, coupled with the fact that youngstellar objects show intense X-ray emission, allows combined IR and X-ray studies tocharacterize stellar regions revealing the entire population of the cloud. A study of thistype, combining observations in X-rays, infrared and optical photometry will be carriedout to study the population of NGC 2023 and Orion B...
