Scientific paper

The paper presents calculations of the evolution of a 20 solar mass star
for various assumptions concerning opacities, energy generation,
convection, and mass loss. An attempt is made to determine which factors
favor a blue supergiant progenitor and which do not. Consideration is
given to the reasons for the early evolution of the Sk -69.202 deg.
