'Quiet' pulsar suddenly reveals three glitches in 15 years of observations
Using more than 15 years of observations from the Parkes radio telescope, astronomers detected three rotational glitches in the pulsar PSR J1637−4642—a young neutron star that had shown no signs of glitches since its discovery.
Using more than 15 years of observations from the Parkes radio telescope, astronomers detected three rotational glitches in the pulsar PSR J1637−4642—a young neutron star that had shown no signs of glitches since its discovery.
The short version
- The three glitches included one that changed its rotation rate by nearly 3 parts per million.
- Their paper was posted to the arXiv preprint server on Aug.
- It has been accepted for publication in the Astrophysical Journal Letters.
