The SUrvey for Pulsars and Extragalactic Radio Bursts IV: Discovery and polarimetry of a 12.1-second radio pulsar

We report the discovery of PSR~J2251-3711, a radio pulsar with a spin period of 12.1 seconds, the second longest currently known. Its timing parameters imply a characteristic age of 15 Myr, a surface magnetic field of 1.3 \times 10^{13}~G and a spin-down luminosity of 2.9 \times 10^{29}~\mathrm{erg~s}^{-1}. Its dispersion measure... Show more
