  It was proved by Karch and Pilarzyc that Landau solutions are asymptotically
stable under any $L^2$-perturbation. In our earlier work with L. Li, we have
classified all $(-1)$-homogeneous axisymmetric no-swirl solutions of
incompressible stationary Navier-Stokes equations in three dimension which are
smooth on the unit sphere minus the south and north poles. In this paper, we
study the asymptotic stability of the least singular solutions among these
solutions other than Landau solutions, and prove that such solutions are
asymptotically stable under any $L^2$-perturbation.
