Radial velocity, viscous torque, and surface density radial profiles for the simplified NS disk model as described in Appendix F. The profiles are taken at the time moment 0.5 Myr after the start of the wind exponential growth. Before that, the disk has been accumulated from the wind with the constant rate Ṁ_w = 5 x 10⁻⁸ M_⊙ yr⁻¹ during 5 Myr. The solid curves with different colors correspond to different wind variation timescales, $t_{\text{w}}\equiv {\dot{M}}_{\text{w}}/{\ddot{M}}_{\text{w}}$. The black, yellow, cyan, green, and red curves represent the cases of t_w = 5.0,1.0,0.5,0.3,0.2 Myr, respectively. The solid blue curve shows the solution for the constant wind rate. The dashed blue curve shows the QSD solution obtained for Ṁ_w = 5 x 10⁻⁸ M_⊙ yr⁻¹. The dashed red curve shows the QSD solution obtained for the instant value of the wind rate attained after 0.5 Myr of its exponential growth with t_w = 0.2 Myr. The initial donor mass M₁ = 7.0 M_⊙, the binary separation is constant a = 100 AU. In all cases, the disk satisfies the floating outer boundary condition (12).
