LMC blue supergiants analysed by Urbaneja et al. (2017) are plotted with circles in the log g_F − M_bol plane. The colour of the circles have the same meaning as in Fig. 7. The blue straight line labelled as G2_b is the lower boundary of the FGLR of BSGs in Local group galaxies (Meynet et al. 2015b). Blue parts (log T_eff >  3.9) of some evolutionary tracks with Z = 0.006 are also plotted, where thick line parts indicate where radial pulsations are excited. The labels ‘S0’ and ‘S4’ refer to models with an initial rotation rate of 0 and 0.4 of the critical one, respectively. Some LBVs are plotted with filled squares for comparison, which clearly indicate that LBVs have experienced significant mass losses.
