Ratios of dust characteristics at several evolution times after the burst onset to those of the model without burst (orange curves). The columns from left to right correspond to the evolution times t = 0.1 kyr, t = 1 kyr and t = 2 kyr after the burst onset in model 2. Rows from top to bottom show the ratios of the azimuthally averaged grown dust surface density, small dust surface density, and maximum grain size. The blue lines show the unity ratios for convenience.
