Fig. 7


HRD positions of the all known single (Paper I) and binary (this paper) SMC WR stars. The big symbols correspond to the binaries analyzed here, while circled smaller symbols correspond to putatively single stars. Plotted are evolutionary tracks (Eldridge et al. 2008) calculated for single stars at a metallicity of Z = 0.004 assuming no mixing (left panel) and chemically homogeneous evolution (right panel). The colors and symbols code the hydrogen abundance and WR type, as described in the legend. The WR phase is defined at XH< 0.6. Tracks which correspond to the solutions found are shown in color.
