Top left (a): the accretion rate onto the star versus time starting from disk formation. Bottom left (b): similar to the top-left panel, but for a time interval t = [0.149, 0.150] Myr. Orange rectangles mark the burst analyzed in Fig. 8. Right (c): space–time diagram of the azimuthally averaged ionization fraction. The white contour line delineates the dead zone boundary. The time is counted from the instance of disk formation.
