HRD of our sample of LMC stars. As explained in the inlet, different symbols represent WNL and WNE stars, respectively. Binaries are also included, but distinguished by different symbols; their spectra have been analyzed as if they were single stars. The five O-type stars in our sample are plotted with their own symbols. Among the WN stars, the color codes the hydrogen mass fraction as defined in the inlet. The zero-age main sequences (ZAMS) for hydrogen-rich and pure-helium stars are shown for orientation.
