A pulsar from pulsa ting r adio source [1] [2] is a highly magnetized rotating compact star usually neutron stars but also white dwarfs that emits beams of electromagnetic radiation out of its magnetic poles.

Neutron stars are very dense and have short, regular rotational periods. This produces a very precise interval between pulses that ranges from milliseconds to seconds for an individual pulsar. Pulsars are one of the candidates for the source of ultra-high-energy cosmic rays. See also centrifugal mechanism of acceleration. The periods of pulsars make them very useful tools for astronomers.

Observations of a pulsar in a binary neutron star system were used to indirectly confirm the existence of gravitational radiation. In , certain types of pulsars were detected that, at that time, exceeded the accuracy of atomic clocks in keeping time. Signals from the first discovered pulsar were initially observed by Jocelyn Bell while analyzing data recorded on August 6, from a newly commissioned radio telescope that she helped build.

Initially dismissed as radio interference by her supervisor, Antony Hewish , developer of the telescope, [5] [6] the fact that the signals always appeared at the same declination and right ascension soon ruled out a terrestrial source. No astronomical object of this nature had ever been observed before.

On December 21, Bell discovered a second pulsar, quashing speculation that these might be signals beamed at earth from an extraterrestrial intelligence. When observations with another telescope confirmed the emission, it eliminated any sort of instrumental effects. At this point, Bell said of herself and Hewish that "we did not really believe that we had picked up signals from another civilization, but obviously the idea had crossed our minds and we had no proof that it was an entirely natural radio emission.

It is an interesting problem—if one thinks one may have detected life elsewhere in the universe, how does one announce the results responsibly? It was not until a second pulsating source was discovered in a different part of the sky that the "LGM hypothesis" was entirely abandoned.

Although CP emits in radio wavelengths , pulsars have subsequently been found to emit in visible light, X-ray , and gamma ray wavelengths. An entirely novel kind of star came to light on Aug. Now it is thought to be a novel type between a white dwarf and a neutron [star]. The name Pulsar is likely to be given to it. Hewish told me yesterday: ' I am sure that today every radio telescope is looking at the Pulsars. The existence of neutron stars was first proposed by Walter Baade and Fritz Zwicky in , when they argued that a small, dense star consisting primarily of neutrons would result from a supernova.

Moreover, the Crab pulsar is so named because it is located at the center of the Crab Nebula, consistent with the prediction of Baade and Zwicky.

Bell claims no bitterness upon this point, supporting the decision of the Nobel prize committee. In , Joseph Hooton Taylor, Jr. This pulsar orbits another neutron star with an orbital period of just eight hours. Einstein 's theory of general relativity predicts that this system should emit strong gravitational radiation , causing the orbit to continually contract as it loses orbital energy.

Observations of the pulsar soon confirmed this prediction, providing the first ever evidence of the existence of gravitational waves. As of , observations of this pulsar continue to agree with general relativity.

MSPs are believed to be the end product of X-ray binaries. Owing to their extraordinarily rapid and stable rotation, MSPs can be used by astronomers as clocks rivaling the stability of the best atomic clocks on Earth. Factors affecting the arrival time of pulses at Earth by more than a few hundred nanoseconds can be easily detected and used to make precise measurements.

Physical parameters accessible through pulsar timing include the 3D position of the pulsar, its proper motion , the electron content of the interstellar medium along the propagation path, the orbital parameters of any binary companion, the pulsar rotation period and its evolution with time. These are computed from the raw timing data by Tempo , a computer program specialized for this task. After these factors have been taken into account, deviations between the observed arrival times and predictions made using these parameters can be found and attributed to one of three possibilities: intrinsic variations in the spin period of the pulsar, errors in the realization of Terrestrial Time against which arrival times were measured, or the presence of background gravitational waves.

Scientists are currently attempting to resolve these possibilities by comparing the deviations seen between several different pulsars, forming what is known as a pulsar timing array. The goal of these efforts is to develop a pulsar-based time standard precise enough to make the first ever direct detection of gravitational waves. This discovery presented important evidence concerning the widespread existence of planets outside the Solar System , although it is very unlikely that any life form could survive in the environment of intense radiation near a pulsar.

In , AR Scorpii was identified as the first pulsar in which the compact object is a white dwarf instead of a neutron star. Initially pulsars were named with letters of the discovering observatory followed by their right ascension e. CP As more pulsars were discovered, the letter code became unwieldy, and so the convention then arose of using the letters PSR Pulsating Source of Radio followed by the pulsar's right ascension and degrees of declination e. Pulsars appearing very close together sometimes have letters appended e.

The modern convention prefixes the older numbers with a B e. All new pulsars have a J indicating Pulsars that were discovered before tend to retain their B names rather than use their J names e. Recently discovered pulsars only have a J name e. All pulsars have a J name that provides more precise coordinates of its location in the sky. The events leading to the formation of a pulsar begin when the core of a massive star is compressed during a supernova , which collapses into a neutron star.

The neutron star retains most of its angular momentum , and since it has only a tiny fraction of its progenitor's radius and therefore its moment of inertia is sharply reduced , it is formed with very high rotation speed. A beam of radiation is emitted along the magnetic axis of the pulsar, which spins along with the rotation of the neutron star. The magnetic axis of the pulsar determines the direction of the electromagnetic beam, with the magnetic axis not necessarily being the same as its rotational axis.

This misalignment causes the beam to be seen once for every rotation of the neutron star, which leads to the "pulsed" nature of its appearance. In rotation-powered pulsars, the beam is the result of the rotational energy of the neutron star, which generates an electrical field from the movement of the very strong magnetic field, resulting in the acceleration of protons and electrons on the star surface and the creation of an electromagnetic beam emanating from the poles of the magnetic field.

When a pulsar's spin period slows down sufficiently, the radio pulsar mechanism is believed to turn off the so-called "death line". This turn-off seems to take place after about 10— million years, which means of all the neutron stars born in the Though the general picture of pulsars as rapidly rotating neutron stars is widely accepted, Werner Becker of the Max Planck Institute for Extraterrestrial Physics said in , "The theory of how pulsars emit their radiation is still in its infancy, even after nearly forty years of work.

Three distinct classes of pulsars are currently known to astronomers , according to the source of the power of the electromagnetic radiation:. Although all three classes of objects are neutron stars, their observable behavior and the underlying physics are quite different. There are, however, some connections. For example, X-ray pulsars are probably old rotationally-powered pulsars that have already lost most of their power, and have only become visible again after their binary companions had expanded and begun transferring matter on to the neutron star.

The process of accretion can, in turn, transfer enough angular momentum to the neutron star to "recycle" it as a rotation-powered millisecond pulsar. As this matter lands on the neutron star, it is thought to "bury" the magnetic field of the neutron star although the details are unclear , leaving millisecond pulsars with magnetic fields —10, times weaker than average pulsars.

This low magnetic field is less effective at slowing the pulsar's rotation, so millisecond pulsars live for billions of years, making them the oldest known pulsars. Millisecond pulsars are seen in globular clusters, which stopped forming neutron stars billions of years ago. Of interest to the study of the state of the matter in a neutron star are the glitches observed in the rotation velocity of the neutron star.

One model put forward to explain these glitches is that they are the result of " starquakes " that adjust the crust of the neutron star. Models where the glitch is due to a decoupling of the possibly superconducting interior of the star have also been advanced. In both cases, the star's moment of inertia changes, but its angular momentum does not, resulting in a change in rotation rate.

When two massive stars are born close together from the same cloud of gas, they can form a binary system and orbit each other from birth. If those two stars are at least a few times as massive as our sun, their lives will both end in supernova explosions. The more massive star explodes first, leaving behind a neutron star. If the explosion does not kick the second star away, the binary system survives.

The neutron star can now be visible as a radio pulsar, and it slowly loses energy and spins down. Later, the second star can swell up, allowing the neutron star to suck up its matter. The matter falling onto the neutron star spins it up and reduces its magnetic field. This is called "recycling" because it returns the neutron star to a quickly-spinning state. Finally, the second star also explodes in a supernova, producing another neutron star.

If this second explosion also fails to disrupt the binary, a double neutron star binary is formed. Otherwise, the spun-up neutron star is left with no companion and becomes a "disrupted recycled pulsar", spinning between a few and 50 times per second.

The discovery of pulsars allowed astronomers to study an object never observed before, the neutron star. This kind of object is the only place where the behavior of matter at nuclear density can be observed though not directly.

Also, millisecond pulsars have allowed a test of general relativity in conditions of an intense gravitational field. Pulsar maps have been included on the two Pioneer plaques as well as the Voyager Golden Record. They show the position of the Sun , relative to 14 pulsars, which are identified by the unique timing of their electromagnetic pulses, so that our position both in space and in time can be calculated by potential extraterrestrial intelligences. Moreover, pulsar positioning could create a spacecraft navigation system independently, or be used in conjunction with satellite navigation.

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 and locations. The advantage of using X-ray signals over radio waves is that X-ray telescopes can be made smaller and lighter.

Generally, the regularity of pulsar emission does not rival the stability of atomic clocks. This stability allows millisecond pulsars to be used in establishing ephemeris time [48] or in building pulsar clocks. Timing noise is the name for rotational irregularities observed in all pulsars.

This timing noise is observable as random wandering in the pulse frequency or phase. The radiation from pulsars passes through the interstellar medium ISM before reaching Earth. The resulting changes to the pulsar's radiation provide an important probe of the ISM itself.

Because of the dispersive nature of the interstellar plasma , lower-frequency radio waves travel through the medium slower than higher-frequency radio waves. The resulting delay in the arrival of pulses at a range of frequencies is directly measurable as the dispersion measure of the pulsar. The dispersion measure is the total column density of free electrons between the observer and the pulsar,.
