Properties of the different populations of dust present in the model.

Population a ξ Dust-to-gas (cloud) Processed dust fraction Name
1 1 µm 3 g cm−3 1.5 × 10−3 Solar nebula composition
2 1 µm 3 g cm−3 3.5 × 10−3 Solar nebula composition
3 1 µm 3 g cm−3 89% Refractory-depleted
4 600 µm 3 g cm−3 3% Amoeboid Olivine Aggregates (AOAs)
5 2500 µm 3 g cm−3 8% Ca-Al-Rich Inclusions (CAIs)

Notes. Listed are the grain size a, the internal grain density ξ, the dust-to-gas ratio within the molecular cloud core, and what fraction of thermally processed population 1 dust is transformed into populations 3–5.
