Evolution of the models computed using the MB3 prescription. Top-left: Donor’s mass vs. orbital period. Top-right: Hertzprung–Russel diagram. Bottom left: Donor’s mass vs. mass transfer rate. Bottom right: Donor’s mass vs. BH spin parameter. Black lines indicate the observed values of the donor mass, luminosity, effective temperature, orbital period, mass transfer rate, and BH spin parameter; shaded grey areas represent their associated uncertainties. The color gradient traces the system’s age during the mass transfer episode.
