Table 1.

Bulk composition of a carbon-enriched planetesimal based on protoplanetary disk evolution modeling around high C/O stars from Moriarty et al. (2014).

Element mol% Material wt%
Si 11.4 SiO2 30.1
Mg 11.4 MgO 20.2
O 45.8 FeOa 27.3
Fe 11.4 Fe 2.2
S 1.9 FeS 7.0
Al 1.4 Al2O3 3.1
Ca 0.7 CaOa 1.7
C 16.0 C 8.4

Notes.

(a)

CaO and FeO are obtained from CaCO3 and Fe2O3 after decarbonation. The starting composition reflects the composition of the powder after the decarbonation.
