XMM-Newton EPIC spectra of KELT-24 acquired at different activity phases. Left: spectra obtained in the first (red) and second observation (black) during quiescent intervals. The bottom panel shows the contributions to χ2 in units of standard deviations. The model is composed of two absorbed APEC thermal components (dotted lines). Right: same but for the spectrum of KELT-24 acquired during the flare.
