Abstract

Hot massive stars constitute an important class of objects amongstellar populations. Diffraction limited high dynamic imaging(HDI) with 8-10 m class telescopes of fine structures which oftencharacterize their extended nebulosities can trace back thehistory of their mass-loss, therefore the evolution of the centralstar across the HRD. Since these stars are among the most luminousstars and display unique emission spectral features in galaxies athigh redshift, they can serve as natural candles to estimatecosmological distances through the Wind-momentum LuminosityRelation (WLR, Kudritzki et al. 2000). In thispaper I develop the context of massive stars HDI and derive somegeneral instrumental specifications for coronagraphic adaptiveoptics.
