    en.wikipedia.org/wiki/Pulsar

    The longest period neutron star pulsar, PSR J0901-4046, with a period of 75.9 seconds. The longest period pulsar, at 118.2 seconds, as well as one of the only known two white dwarf pulsars, AR Scorpii. [68] The first white dwarf pulsar AE Aquarii. [69] [70] The pulsar with the most stable period, PSR J0437−4715

  3. List of neutron stars - Wikipedia

    en.wikipedia.org/wiki/List_of_Neutron_stars

    Neutron stars can be classified as pulsars if they are magnetized, if they rotate, and if they emit beams of electromagnetic radiation out of their magnetic poles. [4] They may include soft gamma repeaters (SGR) and radio-quiet neutron stars , as well as pulsars such as radio pulsars , recycled pulsars , low mass X-ray pulsars, and accretion ...

  4. PSR B1620−26 b - Wikipedia

    en.wikipedia.org/wiki/PSR_B1620%E2%88%9226_b

    About half a billion years ago, the newly captured star began to expand into a red giant (see stellar evolution). Typical pulsar periods for young pulsars are of the order of one second, and they increase with time; the very short periods exhibited by so-called millisecond pulsars are due to the transfer of material from a binary companion. The ...

  5. PSR B1919+21 - Wikipedia

    en.wikipedia.org/wiki/PSR_B1919+21

    PSR B1919+21 is a pulsar with a period of 1.3373 seconds [4] and a pulse width of 0.04 seconds. Discovered by Jocelyn Bell Burnell on 28 November 1967, it is the first discovered radio pulsar. [5]

  6. Binary pulsar - Wikipedia

    en.wikipedia.org/wiki/Binary_pulsar

    An intermediate-mass binary pulsar (IMBP) is a pulsar-white dwarf binary system with a relatively long spin period of around 10–200 ms consisting of a white dwarf with a relatively high mass of approximately . [7] The spin periods, magnetic field strengths, and orbital eccentricities of IMBPs are significantly larger than those of low mass binary pulsars (LMBPs). [7]

  7. Hulse–Taylor pulsar - Wikipedia

    en.wikipedia.org/wiki/Hulse–Taylor_pulsar

    The pulsar and its neutron star companion both follow elliptical orbits around their common center of mass. The period of the orbital motion is 7.75 hours, and the two neutron stars are believed to be nearly equal in mass, about 1.4 solar masses. Radio emissions have been detected from only one of the two neutron stars.

  8. X-ray pulsar - Wikipedia

    en.wikipedia.org/wiki/X-ray_pulsar

    An X-ray pulsar is a type of binary star system consisting of a typical star (stellar companion) in orbit around a magnetized neutron star.The magnetic field strength at the surface of the neutron star is typically about 10 8 Tesla, over a trillion times stronger than the strength of the magnetic field measured at the surface of the Earth (60 μT).

  9. Millisecond pulsar - Wikipedia

    en.wikipedia.org/wiki/Millisecond_pulsar

    2. The massive star explodes, leaving a pulsar that eventually slows down, turns off, and becomes a cooling neutron star. 3. The Sun-like star eventually expands, spilling material on to the neutron star. This "accretion" speeds up the neutron star's spin. 4. Accretion ends, the neutron star is "recycled" into a millisecond pulsar.
