Notes. In these calculations we assumed a constant convective velocity: v_conv = 80 km s^-1.

Density and ¹²C mass fraction at the point that crosses first the dynamical curve.

^(b)

Resulting conditions at runaway: minimum initial temperature of the bubble that runs away, T_rw, runaway radius, r_rw, and runaway time, t_rw.
