Spin-down evolution for an NS with a 0.01 s initial spin period. In this and following figures, solid, dashed, and dotted lines represent the ejector, supersonic propeller, and accretor phases, respectively. Symbol * represents the transition of evolutionary stages. The shaded area and the horizontal line mark the age and the spin period of SXP 1062, respectively. From the top to the bottom, the initial magnetic field is B _i = 7 × 10 ¹⁴ G, 3 × 10 ¹⁴ G, 10 ¹⁴ G, and 3 × 10 ¹² G.
