Effective condensation temperatures (K) of C (left) and S (right) as a function of the devolatilisation trend, in the shape of Eq. (4). The bulk disk composition is solar (Lodders 2003), adjusting only C and Ο abundances such that bulk disk C/O ratios are 0.8 (top) and 0.9 (bottom), while conserving ${10}^{A_C}+{10}^{A_O}$. We show T_D = 10^−β/α rather than parameter β on the y-axis. In addition, we show the lowest T_D in which C may still condense. The devolatilisation trends of Earth (yellow diamond), Mars (red circle), and Vesta (blue square) are indicated.
