The main question in our understanding of the nature of W R stars is: which stars are their progenitors and how do they evolve to reach the WR stage? We have some ideas about progenitor's masses and, by mass luminosity relations, about their brightness when they are 0 stars. But, it is difficult to say anything for their possible Red phase.
