Caption: Figure 7.

Red lines: spin-down luminosity for a supramassive NS remnant with magnetic field B = 10¹³–10¹⁶ G. Black squares: GW170817 bolometric luminosity from Cowperthwaite et al. (2017). Blue filled circles: X-ray luminosity. The spin-down luminosity is always larger than the bolometric energy release from GW170817 at early times, which argues against a long-lived magnetar remnant.
