Symbiotic stars in X-rays. II. Faint sources detected with XMM-Newton and Chandra

We report the detection from four symbiotic stars that were not known to be X-ray sources. These four object show a β-type X-ray spectrum, that is, their spectra can be modeled with an absorbed optically thin thermal emission with temperatures of a few million degrees. Photometric series obtained wi...
