Determination of the masses of the components of the HDE 226868/Cyg X-1 binary system
Determination of the masses of the components of the HDE 226868/Cyg X-1 binary system
Recent determination of the distance to HDE 226868/Cyg X-1 binary system (Reid et al., 2011) and more precise determination of the effective temperature of HDE 226868 (Caballero- Nieves et al., 2009) permit a more accurate estimate of the masses of both components. Using up to date evolutionary models, I obtain …
