XMM-Newton EPIC MOS1 (black) and EPIC MOS2 (red) spectra of V5116 Sgr, plotted together with the best fitted white dwarf (WD) atmosphere models.
| (A) | Low-flux spectra fit with a carbon/oxygen WD atmosphere model |
| (B) | Low-flux spectra fit with an oxygen/neon WD atmosphere model |
| (C) | High-flux spectra fit with an oxygen/neon WD atmosphere model |
Below each spectrum the deviation of the model from the spectrum is plotted. The results show that the carbon/oxygen atmosphere model does not fit the observations (A).
The oxygen/neon model fits both the low- and high-flux state of V5116 Sgr and the atmosphere temperature of the fitted model was found to be 6.1±0.1 × 105 K, both for the low- and high-flux state (B & C).
