  2. Neutron star - Wikipedia

    en.wikipedia.org/wiki/Neutron_star

    Neutron stars are known that have rotation periods from about 1.4 ms to 30 s. The neutron star's density also gives it very high surface gravity, with typical values ranging from 10 12 to 10 13 m/s 2 (more than 10 11 times that of Earth). [21]

  3. Neutron Star Interior Composition Explorer - Wikipedia

    en.wikipedia.org/wiki/Neutron_star_Interior...

    The Neutron Star Interior Composition ExploreR (NICER) is a NASA telescope on the International Space Station, designed and dedicated to the study of the extraordinary gravitational, electromagnetic, and nuclear physics environments embodied by neutron stars, exploring the exotic states of matter where density and pressure are higher than in atomic nuclei.

  4. List of neutron stars - Wikipedia

    en.wikipedia.org/wiki/List_of_Neutron_stars

    Zooming to RX J1856.5−3754 which is one of the Magnificent Seven and, at a distance of about 400 light-years, the closest-known neutron star. Neutron stars are the collapsed cores of supergiant stars. [1] They are created as a result of supernovas and gravitational collapse, [2] and are the second-smallest and densest class of stellar objects ...

  5. RX J1856.5−3754 - Wikipedia

    en.wikipedia.org/wiki/RX_J1856.5%E2%88%923754

    Zooming in on the very faint neutron star RX J1856.5–3754 Hubble image of RX J1856.5−3754—the first direct observation of an isolated neutron star in visible light. RX J1856.5−3754 is thought to have formed in a supernova explosion of its companion star about one million years ago and is moving across the sky at 108 km/s.

  6. Magnetar - Wikipedia

    en.wikipedia.org/wiki/Magnetar

    Duncan and Thompson calculated that when the spin, temperature and magnetic field of a newly formed neutron star falls into the right ranges, a dynamo mechanism could act, converting heat and rotational energy into magnetic energy and increasing the magnetic field, normally an already enormous 10 8 teslas, to more than 10 11 teslas (or 10 15 ...

  7. SGR 1806−20 - Wikipedia

    en.wikipedia.org/wiki/SGR_1806%E2%88%9220

    SGR 1806−20 is a magnetar, a type of neutron star with a very powerful magnetic field, that was discovered in 1979 and identified as a soft gamma repeater.SGR 1806−20 is located about 13 kiloparsecs (42,000 light-years) [1] from Earth on the far side of the Milky Way in the constellation of Sagittarius.

  8. Hulse–Taylor pulsar - Wikipedia

    en.wikipedia.org/wiki/Hulse–Taylor_pulsar

    The Hulse–Taylor pulsar (known as PSR B1913+16, PSR J1915+1606 or PSR 1913+16) is a binary star system composed of a neutron star and a pulsar which orbit around their common center of mass. It is the first binary pulsar ever discovered.

  9. Neutron star merger - Wikipedia

    en.wikipedia.org/wiki/Neutron_star_merger

    A neutron star merger is the stellar collision of neutron stars. When two neutron stars fall into mutual orbit, they gradually spiral inward due to the loss of energy emitted as gravitational radiation. [1] When they finally meet, their merger leads to the formation of either a more massive neutron star, or—if the mass of the remnant exceeds ...
