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, ...

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 ...

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, ...

Discovery of the companions of millisecond pulsars

When a star with a mass of roughly ten solar masses finishes its life, it does so in a spectacular explosion known as a supernova, leaving behind as remnant "ash" a neutron star. Neutron stars have masses of one-to-several ...

Binary star system precisely timed with pulsar's gamma-rays

Pulsars are rapidly rotating compact remnants born in the explosions of massive stars. They can be observed through their lighthouse-like beams of radio waves and gamma-rays. Scientists at the Max Planck Institute for Gravitational ...

Fermi finds a 'transformer' pulsar

(Phys.org) —In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at the same time the ...

With a deadly embrace, 'spidery' pulsars consume their mates

(Phys.org) —Black widow spiders and their Australian cousins, known as redbacks, are notorious for their tainted love, expressed as an unsettling tendency to kill and devour their male partners. Astronomers have noted similar ...

Triple millisecond pulsar laboratory challenges theory

(Phys.org) —Millisecond pulsars are old neutron stars, which rotate several hundred times per second. They are often found in binary systems and their existence can be explained by mass transfer from a companion star. The ...
