P₀ − Ṗ diagram showcasing all isolated and binary pulsars, and highlighting all known DNS systems and candidates (Table 1). The dashed lines indicate the characteristic age τ_c, the surface magnetic field B_surf and the spin-down luminosity. J1208−5936 falls at the bottom of the mildly recycled population. All data points except J1208−5936 have been retrieved from the Australia Telescope National Facility (ATNF) website.
