\label{fig:f8}On the top left-hand panel, surface density profile of a disk orbiting a binary with a total mass \(M_{c}=1\) M\({}_{\odot}\) and mass ratio \(q=1\) is shown for different times, as labeled. Solid and dashed curves are corresponding to the cases with the external and the internal winds, respectively. The adopted input parameters are \(s=\frac{1}{2}\)\(\alpha=0.01\)\(f=1.0\),and \(a_{\rm b}=0.2\)AU. On the top right-hand panel, disk radius as a function of time is shown. On the bottom row, profiles of the disk mass (left) and evolutionary track in the plane of disk mass and radius (right) are shown for the presented solutions.
