Formation efficiency of Cyg X-3 candidates (Singh et al. 2002; Koljonen & Maccarone 2017) for each set of binaries simulated at the two solar metallicity values considered in this work: Z = 0.02 (left) and Z = 0.014 (right). We distinguish Cyg X-3 candidates hosting a BH (upper panels) or an NS (lower panels). We highlight with darker shades the Cyg X-3 candidates that are BCO progenitors.
