Evolution of luminosity and temperature of the "cool" and "warm" thermal components of the Tidal Disruption Event AT2020ocn

TOP: 0.3-2 keV luminosity of the cool (blue), warm (green) and the overall emission (black) based on the model fits in 0.3-1.3 keV band. BOTTOM: Temperature evolution of the two components. The warm component is steadily getting hotter over the last several months. New XMM observations will not only validate this result but will also provide access to the properties of the hard X-ray spectrum (1-10 keV) and tell us about time variability on short (minutes) timescale.
