Pulsar-Driven Jets in Supernovae, Gamma-Ray Bursts, and the Universe

Figure 8

The solution values for (4)–(7). Horizontal: the maximum jet velocity, 𝛽. Left vertical: the maximum range of the polar ejecta. Right vertical axis: the distance from the pulsar to the beginning of the polar ejecta. The line with the steepest slope converts 𝛽 (bottom) to 𝐷+𝑑 (left) or 𝑑 (right), and three values for 𝜃 are marked. The three other lines with moderate slopes constrain the minimum of 𝐷+𝑑 (right end of 74 mas curve) and the maximum of 𝑑 (left end of the 45 mas curve and also read on the left vertical axis) from offset measurements of the Mystery Spot, which is assumed to be a jet-driven plume within the polar ejecta. Five values of 𝛼, from 0.3 to 0.7, are tic-marked on the four curves.
