    en.wikipedia.org/wiki/Pulsar

    X-ray pulsar-based navigation and timing (XNAV) or simply pulsar navigation is a navigation technique whereby the periodic X-ray signals emitted from pulsars are used to determine the location of a vehicle, such as a spacecraft in deep space. A vehicle using XNAV would compare received X-ray signals with a database of known pulsar frequencies ...

    Neutron stars are stellar remnants produced when a star of around 8–9 solar masses or more explodes in a supernova at the end of its life. They are usually produced by stars of less than 20 solar masses, although a more massive star may produce a neutron star in certain cases.

    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.

    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 ...

    Schematic view of a pulsar. The sphere in the middle represents the neutron star, the curves indicate the magnetic field lines, the protruding cones represent the emission beams and the green line represents the axis on which the star rotates. Supernovae sometimes leave behind dense spinning neutron stars called pulsars.

  9. PSR J1748−2446ad - Wikipedia

    en.wikipedia.org/wiki/PSR_J1748%E2%88%922446ad

    The pulsar is located in a globular cluster of stars called Terzan 5, located approximately 18,000 light-years from Earth in the constellation Sagittarius. It is part of a binary system and undergoes regular eclipses with an eclipse magnitude of about 40%. Its orbit is highly circular, with a 26-hour period.
