Surface density profile of the proto planetary disk at two moments in time for two supernovae SN10a (green) and the much brighter SN11aof (red). The former was at a distance of d = 0.1 pc and with an impact angle of Θ = 60°, the latter at a distance of d = 0.4 pc and with an angle of Θ = 15°. The dark blue curve indicates the surface density distribution of the known planetesimals in the solar system (see http://minorplanetcenter.net/data). The total mass of the Sun’s planetesimal disk was normalized to the initial disk mass in our simulations (0.01 M_⊙). The initial density profile of the disk (light blue) is the same for each model. The thin periwinkle-colored horizontal line indicates the minimum disk-mass we adopted, truncating the solar system’s disk at about 55 au.
