Millisecond pulsars

When a star with a mass of roughly ten solar masses finishes its life, it explodes as a supernova, leaving behind a neutron star as remnant "ash." Neutron stars have masses of one-to-several suns but they are tiny in diameter, ...

Pulsar discovered in an ultraluminous X-ray source

(Phys.org)—A team of European astronomers has discovered a new pulsar in a variable ultraluminous X-ray source (ULX) known as NGC 7793 P13. The newly found object is the third ultraluminous X-ray pulsar detected so far, ...

Astronomers detect glitch in a millisecond pulsar

(Phys.org)—European astronomers have uncovered evidence of a small glitch in the spin of a millisecond pulsar. According to a research paper published on June 13 on arXiv.org, the pulsar, designated PSR J0613-0200, exhibits ...

Pulsar web could detect low-frequency gravitational waves

The recent detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) came from two black holes, each about 30 times the mass of our sun, merging into one. Gravitational waves span ...

The 'glitching' of the Vela pulsar

(Phys.org)—A team of Australian astronomers has conducted an intensive observation of a curious young pulsar to investigate changes in its rotation frequency known as 'glitching'. Located about 910 light years from the ...

Astronomers find six new millisecond pulsars

(Phys.org)—NASA's Fermi Gamma-ray Space Telescope has once again proven that it is an excellent tool to search for rotating neutron stars emitting beams of electromagnetic radiation, known as pulsars. A team of astronomers, ...
