Fig. 3


Zoom on the 6.0–7.5 keV spectral band of the high-state EPIC-pn spectrum of HD 45314. The histogram yields the best-fit 1-T thermal model including an extra Gaussian to fit the fluorescent Fe Kα line. The theoretical energies of the fluorescent lines of Fe I-XVII as well as the energies of the He-like lines of Fe XXV and the H-like Fe XXVI Lyα lines are indicated by the tick marks. The simultaneous presence of the latter features is the signature of a thermal plasma with kTh near 10 keV.
