Fig. 5


Dependence of final abundances on the accretion rates and on the adopted convection theory for the case of GD 133. Solid lines stand for results obtained by using the classical mixing length convection theory (MLT). Dashed lines connect points obtained by implementing a double diffusion convection theory (GNA). Points with error bars refer to the observed abundances reported by Xu et al. (2014). For GD 133, Fe was not detected by Xu et al. (2014), thus no point was added in the corresponding figure. [X/H] = log n(X) /n(H), the logarithmic number ratio of the abundance of element X relative to the abundance of H.
