Mass distribution of particles (normalised such that the integral over the logarithmic radius is always unity) just outside of the ice line at 1.8 (yellow line), 2.1 (red line), and 3.6 au (blue line) after the ice line has returned to its quiescent state in a scenario with a cooling time of t_cool = 100 yr. We indicate the particle size for the longer cooling time of 1000 yr with circles. The black line shows the mass distribution of bare silicate particles.
