PSR J1119−6127 is a high magnetic field (high-B), rotation-powered
radio pulsar discovered in the Parkes multibeam pulsar
survey. Magnetar-like X-ray bursts from PSR J1119−6127 were detected
by the Fermi/Gamma-ray Burst Monitor on 2016 July 27, which makes it
the first rotation-powered, radio pulsar to show magnetar-like
activities. Shi Dai (CASS) has led a team which
report in their paper
monitoring of the spin frequency, flux density and pulse profile evolution
of PSR J1119−6127 following the X-ray bursts, using data taken with
the Parkes radio telescope.The peculiar spin frequency evolution is
clearly different from what has been observed from magnetars and
high-magnetic field pulsars before, and therefore provides us the best case to
study the connection between high-magnetic field pulsars and magnetars.
The figure above shows the pulsar spin frequency, spin-frequency derivative
and flux density as a function of time. Yellow regions show the
radio-quiet period after the X-ray burst. Black dashed lines indicate
the peak flux density.
