The chromospheric-coronal emission of lower Main-Sequence single and binary stars can be correlated with an activity parameter of type R - g(B - V)/P, where P is the rotation or orbital period and g(B - V) a function of the color resembling the convective turnover time. Observations indicate that the active region area coverage filling factor grows as R-squared, and the whole stellar surface becomes filled with closed loop structures at R of about 3. A braking formula is proposed to include all periods (R in the approximate range from 0.1 d to 30 d) and spectral types F-M. On the basis of this equation, the mass transfer rates in compact binaries (driven by the gradual loss of orbital angular momentum) are discussed. It is concluded that the magnetic braking has good chances of being that mechanism which drives the mass transfer in cataclysmic variables and galactic bulge X-ray sources.
