NEUTRON STAR
| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
A star that has collapsed under its own gravity; it is composed of neutrons
Classified under:
Nouns denoting natural objects (not man-made)
Hypernyms ("neutron star" is a kind of...):
star ((astronomy) a celestial body of hot gases that radiates energy derived from thermonuclear reactions in the interior)
Hyponyms (each of the following is a kind of "neutron star"):
pulsar (a degenerate neutron star; small and extremely dense; rotates very fast and emits regular pulses of polarized radiation)
Context examples:
Kilonovae may also result from the merger of a black hole and neutron star, but it is unknown whether such an event would yield a different signature in X-ray, infrared, radio and optical light observations.
(Astronomers find a golden glow from a distant stellar collision, National Science Foundation)
The favored explanation for short gamma-ray bursts is that they're caused by a jet of debris moving near the speed of light produced in the merger of neutron stars or a neutron star and a black hole.
(NASA Missions Catch First Light from a Gravitational-Wave Event, NASA)
Its subsequent interaction with the neutron star could have heated the pulsar and slowed its rotation.
(Hubble Uncovers Never-Before-Seen Features Around a Neutron Star, NASA)
Astronomers suspected that, if heavier elements did form in neutron star collisions, signatures of those elements could be detected in kilonovae, the explosive aftermaths of these mergers.
(First identification of a heavy element born from neutron star collision, ESO)
A neutron star is the crushed core left behind when a star much more massive than the Sun runs out of fuel, collapses under its own weight and explodes as a supernova.
(NASA’s Fermi Mission Links Nearby Pulsar’s Gamma-ray ‘Halo’ to Antimatter Puzzle, NASA)
But if the neutron star spins especially fast, those magnetic fields can create a barrier, making it impossible for material to reach the star's surface.
(NASA Satellite Spots a Mystery That's Gone in a Flash, The Titi Tudorancea Bulletin)
A magnetic field would distort the flow of incoming material close to the neutron star.
(NuSTAR Helps Find Universe's Brightest Pulsars, NASA)
This discovery allowed a team led by Frédéric Vogt, an ESO Fellow in Chile, to track down the first ever isolated neutron star with low magnetic field located beyond our own Milky Way galaxy.
(Dead Star Circled by Light, ESO)
If confirmed as a supernova fallback disk, this result could change our general understanding of neutron star evolution.
(Hubble Uncovers Never-Before-Seen Features Around a Neutron Star, NASA)
In 2017, following the detection of gravitational waves passing the Earth, ESO pointed its telescopes in Chile, including the VLT, to the source: a neutron star merger named GW170817.
