Combination of magnetar-powered and interaction contribution of bolometric luminosity of LSQ14mo. The symbol “S” marks the time when spectra were taken, and the green “S” highlights the epoch with a hot continuum seen in the spectrum. Blue squares show the final bolometric light curve integrated from UVW2 to K and fitted with a fully trapped magnetar model in red; black empty circles show the lower limit of assumed magnetar-powered light curve and fitted in blue. The luminosity difference between red and blue magnetar models is an additional energy source in green, which is speculated to come from the interaction between the SN ejecta and a thin shell or some clumps inside the CSM likely originating from a massive star mass loss before the SN explosion.
