A zoomed-in version of the Hertzsprung-Russell diagram for the single (circle) and binary (triangle) supergiants. Also shown are the LMC evolutionary tracks of Brott et al. (2011) for v_o≃ 225 km s^-1, with the initial mass (in units of the solar mass) given on the right hand side. The dark line represents the TAMS. The stars highlighted in green are far enough from the TAMS line that they may be interpreted as core Helium burning objects.
