We detected the spectral signature of extended diffuse emission centered around HD 5005. The diffuse emission has plasma temperatures of about 100 eV for the soft component and as high as 4 keV for the harder component with a luminosity of 1.2−5.8×10^33 erg s^{−1} . The derived electron density can range from ∼ 1−30 cm^{−3} depending on model assumptions. We compare the properties of the diffuse emission to recent X-ray results for other star forming regions which find evidence of charge exchange and also for evidence of radiative recombination. This helps understand the interplay between star forming regions and their surrounding ISM. |
