Evolution of the dust’s disc-integrated flux at 24 μm, as computed with GRaTer for two different initial kick velocities: full line is 1 v_esc and dash-dotted 2 v_esc. The dashed line marks a dust-to-star flux ratio equal to 0.1, taken as our detectability criteria. The X-axis indicates the time after the breakup in years. The right-hand side Y-axis indicates the absolute flux in Jy, while the left-hand side axis displays the ratio of the disc flux to that of the stellar photosphere.
