Robust development thus requires a tight control of the motion and placement of topological defects. In this manuscript, we study a mechanism to control +1 topological defects in an active polar fluid confined to a disk. If activity is localized in an annulus within the disk, the defect moves on a circular trajectory around the center of the disk. Using an ansatz for the polar field, we determine the dependence of the angular spee","authors_text":"Abhinav Singh, Birte C. Geerds, Daniel J. G. Pearce, Frank J\\\"ulicher, Ivo F.
