Rare pulsar unleashes 114 giant pulses in a single hour

Phys.orgIndependentCenter5 hr. ago

Astronomers observed unusual activity from a rare type of pulsar known as a transitional millisecond pulsar, PSR J1227−4853. This neutron star emitted 114 extremely powerful 'giant pulses' within a single hour during 174 hours of radio observations. These pulses are significantly brighter than the pulsar’s usual emissions and represent a rare phenomenon previously seen in only 19 other pulsars. The pulsar exhibits unique characteristics, including a strong magnetic field at its light cylinder and high spin-down luminosity, which suggest a potential connection to the mystery of giant pulse generation. Researchers used data from the Giant Metrewave Radio Telescope (GMRT) to analyze the pulsar's behavior, adding new insights into the dynamics of these celestial objects.

Astronomers using 15 years of data from the Parkes radio telescope discovered three rotational glitches in the pulsar PSR J1637−4642, a young neutron star previously considered 'quiet.' The most significant glitch in 2018 caused a nearly 3 parts-per-million change in its rotation rate. The study, led by Zhaoyi Wang of Xiamen University, suggests these glitches result from angular momentum transfer between the superfluid interior and the solid crust of the neutron star. The findings support existing theories about pulsar behavior and provide insights into the internal structure of neutron stars.
