                         systems having Earth-size planets within their habitable zones 
                         (HZs). First, we selected all known CB systems with confirmed 
                         planets (totaling 22 systems) to calculate the boundaries of their 
                         respective HZs. However, only eight systems had all the data 
                         necessary for the computation of HZ. Then, we numerically explored 
                         the stability within HZs for each one of the eight systems using 
                         test particles. From the results, we selected five systems that 
                         have stable regions inside HZs, namely Kepler-34, 35, 38, 413, and 
                         453. For these five cases of systems with stable regions in HZ, we 
                         perform a series of numerical simulations for planet formation 
                         considering discs composed of planetary embryos and planetesimals, 
                         with two distinct density profiles, in addition to the stars and 
                         host planets of each system. We found that in the case of the 
                         Kepler-34 and 453 systems, no Earth-size planet is formed within 
                         HZs. Although planets with Earth-like masses were formed in 
                         Kepler-453, they were outside HZ. In contrast, for the Kepler-35 
                         and 38 systems, the results showed that potentially habitable 
                         planets are formed in all simulations. In the case of the 
                         Kepler-413 system, in just one simulation, a terrestrial planet 
                         was formed within HZ.",
