Impact-induced melting during accretion of the Earth

Progress in Earth and Planetary Science

Table 3 Starting parameters used for the three N-body accretion simulations (number and masses of embryos and planetesimals, respectively)

Simulation	4:1–0.25–7	4:1–0.5–8	i4:1–0.8–4
No. of embryos	170	87	82
No. of planetesimals	4346	4399	2760
Embryo mass	~0.25 × M _Mars	~0. 5 × M _Mars	~0.2–0.8 × M _Mars ^a
Planetesimal mass	<0.04 × M _Mars	<0.04 × M _Mars	<0.04 × M _Mars

Collision histories of these three simulations are used for calculations of impact-induced melting in this study
^aEmbryo mass increases with increasing heliocentric distance from 0.7 to 3.0 AU
