Abstract
Hot massive stars constitute an important class of objects among
stellar populations. Diffraction limited high dynamic imaging
(HDI) with 8-10 m class telescopes of fine structures which often
characterize their extended nebulosities can trace back the
history of their mass-loss, therefore the evolution of the central
star across the HRD. Since these stars are among the most luminous
stars and display unique emission spectral features in galaxies at
high redshift, they can serve as natural candles to estimate
cosmological distances through the Wind-momentum Luminosity
Relation (WLR, Kudritzki et al. 2000). In this
paper I develop the context of massive stars HDI and derive some
general instrumental specifications for coronagraphic adaptive
optics.
