Crossword clues for pulsar

Longman Dictionary of Contemporary English
▪ It is possible to detect individual pulses from this millisecond pulsar with high signal-to-noise ratio in unbroken trains.
▪ In the standard formation model, millisecond pulsars are formed when a neutron star accretes matter from an evolving companion.
▪ A total of 112 pulse arrival times over a 120-day time interval were collected for this pulsar.
▪ A variant of the suggestion is that the Sun has a pulsar as a companion.
▪ At present, parallax measurements for pulsars are few and barely significant.
▪ It is therefore another compact star, perhaps even a pulsar.
▪ One of the pulsar's original discoverers, Stanislav Djorjovski, reported finding a brighter star coinciding with the pulsar last November.
▪ Subsequent timing observations have shown the pulsar to be in a 5.74-day circular orbit with a low-mass companion.
▪ The pulsar is probably a different object.
▪ The observation of slowing down of the orbital rotation of the binary pulsar 1913+16 is also discussed.
Douglas Harper's Etymology Dictionary

1968, from pulse (n.1), the form on analogy of quasar. When discovered in 1967, they were thought perhaps to be signals from alien civilizations and astronomers informally dubbed them LGM for "Little Green Men."


n. (context star English): A rotating neutron star that emits radio pulses periodically


n. a degenerate neutron star; small and extremely dense; rotates very fast and emits regular pulses of polarized radiation

Pulsar (disambiguation)

A pulsar is a type of star.

Pulsar may also refer to:


A pulsar (short for pulsating radio star) is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. This radiation can be observed only when the beam of emission is pointing toward Earth (much the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance of emission. Neutron stars are very dense, and have short, regular rotational periods. This produces a very precise interval between pulses that range roughly from milliseconds to seconds for an individual pulsar. Pulsars are believed to be one of the candidates of high and ultra-high energy astroparticles (see also Centrifugal mechanism of acceleration).

The precise periods of pulsars make them very useful tools. Observations of a pulsar in a binary neutron star system were used to indirectly confirm the existence of gravitational radiation. The first extrasolar planets were discovered around a pulsar, PSR B1257+12. Certain types of pulsars rival atomic clocks in their accuracy in keeping time.

Pulsar (Marvel Comics)

Pulsar is a fictional character in the Marvel Universe, a member of the Shi'ar Imperial Guard.

Pulsar (watch)

Pulsar is a brand of watch and a division of Seiko Watch Corporation of America (SCA). While Pulsar was the world's first electronic digital watch, today Pulsar watches are usually analog. They generally use the same movements as the lower-end Seikos such as the 7T62 quartz chronograph movement.

Pulsar (video game)

Pulsar is a 1981 arcade game created by Sega/ Gremlin. In it, the player controls a tank in a top-down view maze to fetch keys used to unlock the next level.

Pulsar runs on the Z80 microprocessor. The game was designed and programmed by Larry Clague and Mike Hendricks.

Pulsar (toy)

Pulsar: The Ultimate Man of Adventure was an action figure for boys made by Mattel in 1976. Pulsar was a 14" action figure looked like a handsome middle aged man with short white hair. However once you opened his sweat suit top it revealed that his entire torso was clear plastic which allowed viewing of his internal organs. There was a button on his back that when depressed would make his lungs and heart pump and force simulated blood through some simulated arteries and veins in the body cavity. In addition to having visible innards, Pulsar's head could flip open and a holographic mission disk (a small lenticular plastic disk) could be placed inside. The literature provided with this toy said that this was his mission program disc. There were two versions of the doll, the difference between the two being that the second version of Pulsar had his lower waist and groin painted to match his skin color thus disguising the rubber connectors for where the legs attached to the pelvis. Some also claim that the second version has a more expressive and friendlier face. There never was a back story given to Pulsar, he was just the "Ultimate Man of Adventure". His strange biology could make one think he is an alien, an evolved human cyborg or a combination of these possibilities. The only other toys to be developed for the Pulsar toy line were his nemesis Hypnos: The Ultimate Enemy and Pulsar's Life Systems Center which was a medical bay style wall that Pulsar could be placed inside. Pulsar was patented in 1976 but Mattel toys did not produce him until 1977.

Pulsar (band)

Pulsar is a French progressive rock band whose influences include Pink Floyd and King Crimson, plus classical musicians and composers such as Gustav Mahler.

During the early 1980s, the group performed and composed the music for a Franco‑Austrian musical theatre production. Their most recent album is Memory Ashes (2007).

Pulsar (comics)

Pulsar, in comics, may refer to:

  • Pulsar (Marvel Comics), a member of the Shi'ar Imperial Guard
  • Pulsar (Plor), a member of the Spaceknights
  • Pulsar, a codename of superhero Monica Rambeau
  • Pulsar Stargrave, a DC Comics villain

Usage examples of "pulsar".

Mino had taken to calling the approaching pulsar and its anticipated effects.

Using the stylus from her data slate as a pointer, she indicated the pulsar centered on the screen.

In this case, those beams will intersect with Mestiko as the pulsar moves through the system.

While that portion of Mestiko facing away from the pulsar will be spared from direct exposure, the damage to the entire planet will be catastrophic.

Gelta nation-state, who have taken measures to ensure their secrecy as well as that of the pulsar and the existence of beings from other worlds.

There would be plenty of time to study the pulsar and allow Cameron to complete her work in preparation for deploying the deflector drones.

He already could anticipate the reaction his navigator and close friend would have when he learned of the potential danger they faced in bringing the ship so close to the pulsar and its hazardous effects.

That Celadi had not known of the existence of Apohatsu and the rest of the team was fortunate, in that it obviously would have led to all manner of other questions regarding their presence here, to say nothing about inquiries into their knowledge of the pulsar and whether they might be able to do anything about it.

The transmission ended and the image of Apohatsu was replaced with that of a starfield, with the pulsar depicted as an indistinct red blur at the center of the screen.

Professor Cameron had determined that due to the level of X-ray radiation being emitted by the pulsar, this was the maximum distance the ship could keep and still receive uncorrupted telemetry from the probes once the deflector grid was deployed and began its task of shunting the lethal radiation away from Mestiko.

Kirk ordered, turning toward the forward screen in time to see the image displayed upon it change from that of the pulsar to a computer-generated schematic.

Six smaller white dots corresponded to the positions of the unmanned probes, arrayed in a hexagonal formation between the pulsar and the general direction of Mestiko.

It was how long the probes needed to provide their blanket of protective energy, erected between the pulsar and the endangered planet as both astral bodies made their way through the void.

Mestiko having suffered the worst effects of the pulsar, the surviving elements of planetary governments devastated by the disaster had been struggling to deploy emergency response assets and procedures.

The business arm of the RG was the Pulsar Division, an elite counterintelligence unit.
