Abundance pattern of HIP 56948 (circles) versus condensation temperature. The average of the highly volatile (low T_cond) elements C and O is used as reference. The solid line represents the mean abundance pattern of the 11 solar twins studied by Meléndez et al. (2009) and the dashed line represents the fit to the abundance pattern of HIP 56948. Clearly, HIP 56948 is much closer to the Sun than to other solar twins.
