Survey of Class 0 Protostars in the Smallest Clouds

We propose a survey of five nearby Bok globules to search for Xrays from Class0 protostars. Xrays from Young Stellar Objects are likely to originate from thenear vicinity of the star itself. The detection of the Xrays from Class 0protostars, therefore, is of particular importance, providing direct evidencethat the central star has been born. However, the protostars are usually deeplyembedded within the cloud, so that, even the Xrays were completely absorbed.Bok globules are known as star formation sites surrounded by light and smallmolecular clouds of 10 Mo. The small absorption column of Bok globules gives usan opportunity to search whether Xrays turnon occurs during the Class 0phase and if so, when? truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
