Snapshots of steady-states. Snapshots of steady-states for a low motor attachment rate kA/kD = 1 (left) and a higher rate kA/kD = 30 (right). Conversely, the top line is for fast motors kMτ
= 3.75 × 10-2 and the bottom line for motors 10 times slower. Filaments are shaded light (dark) towards their plus (minus) ends, respectively. These states are referred to as (a) spindle, (b) aster, (c) nematic and (d) semi-aster. The other parameters are P/P0 = 0.03 and kE = kD. Movies of the same parameter values are available from the supplementary information.
