WebMay 20, 2024 · The pulsar’s rotational parameters place it in the right region of the P–Ṗ diagram (see Figure 4), an area where few pulsars have been found to reside. In particular, PSR J0250+5854 falls near/below many of the so-called “pulsar death lines,” beyond which pulsars are not expected to emit coherent radio emission. Webthe so-called radio pulsar “death line” is defined as a line in a two-dimensional pulsar parameter phase space (P −P˙ diagram, P − Bs diagram, or P − Φ diagram, where P is the pulsar period, P˙ the pulsar spin-down rate, Bs the sur-face magnetic field, and Φ the polar cap potential), which
