The ratio of the dust-to-stellar flux as a function of time for six different wavelengths from 5 to 500 microns, including a zoom during the instability – note that each main plot is on a log scale and each zoom-in is on a linear scale. The rough observational limits of the MIPS instrument on NASA’s Spitzer Space Telescope are shown for 25 and 70 μm with the dashed line Trilling et al. (2008). All planetesimal particles were destroyed as of 45 Myr via either collision or ejection so there is no more dust in the system after that point.
