Initial masses of planetesimals and embryos. We show the mass of planetesimals (solid) and embryos (dashed) at initial time t₀, which ranges from ~0.5 Myr in the inner disc to ~1.5 Myr in the outer disc. The planetesimal size is the characteristic size, which follows from the streaming instability IMF, and the embryo size is the single most massive body. The initial sizes for different stellar masses are colour-coded.
