Fractional energy change of the orbit due to winds as a function of initial orbital separation for initially circular orbits. The different lines represent four different systems. Low-mass ratios are shown in black, high-mass ratios in grey. The black, grey, black-dashed, and grey-dashed lines represent systems with initial masses of (2.5 & 1 M_⊙), (2.5 & 2 M_⊙), (5 & 1 M_⊙), and (5 & 4 M_⊙), respectively. If the fractional energy change is larger than unity, the system dissolves.
