A Stellar Remnant with very specific properties.

Pulsar is the name for a Neutron Star that is rotating such that the radio-beaming is detected as it sweeps past the observer.
Please see Degenerate Dwarf section at article Star.

Description

The Neutron Star is one of three main types of stellar remnant:

Neutron Stars form from main-sequence stars of over eight times the mass of Sol and are generally the remnants of a Supernova. Any planet in the same system as a Neutron Star will have been sterilised at that time. Neutron stars should not be closely approached as they have considerable magnetic fields, massive gravity and generally have intense radiation environments nearby. A Neutron Star will typically have a mass between 1.4 M_Sol and ~ 2.1 M_Sol. Escape velocities are over ⅓ the speed of light. When initially formed, a Neutron star will have a rotation rate of about 1000 rps due to conservation of angular momentum. As the electrically charged particles at the surface will generate a dynamo effect at these angular velocities, the Neutron star will typically beam electromagnetic radiation away from it as it rotates, the beams being constrained to a conical region above the magnetic poles due to constriction from relativistic effects. As the Neutron star "pulsar" beams away energy, conservation of energy will cause the neutron star to gradually spin down over time. The rotation rate of a Neutron Star in fact normally decays at a very predicable rate (unless it is being "spun-up" by matter falling from the Accretion Disk of a companion star onto its surface).

Pairs of Neutron Stars that are close together will slowly reduce their separations and will eventually merge to create Black Holes and massive gravity waves. Such mergers are one of the primary mechanisms for the creation of heavy elements in the Universe. Fortunately, such pairs do not exist in the Imperial part of Charted Space.

Stellar Remnants of less than about 1.4 M_Sol will generally form into a White Dwarf instead, while Stellar Remnants larger than about 2-3 M_Sol will form into a Black Hole .

History

Neutron Stars have been known of since before spaceflight.
