Recurrence time of the type-I X-ray bursts observed by IXPE evaluated as the interval between consecutive bursts scaled by a factor of 1 (blue points), 2 (green), and 3 (red) as a function of the persistent count rate observed before the burst C. The dashed line shows the relation Δt_rec = KC^−0.8 with K = 12.75 h. The inset shows the profile of the burst observed starting at MJD 60 377.05969.
