Sentence examples for of the pulsar from inspiring English sources
The X-ray images of the pulsar and the supernova remnant were made last year by the Chandra spacecraft, sent up by the National Aeronautics and Space Administration.
These magnetic poles do not coincide with the rotational poles, and so the rotation of the pulsar swings the radiation beams around.
Irregularities in the radio emissions of the pulsar PSR 1913 + 16 led them to deduce that the pulsar had a companion neutron star with which it was locked in a tight orbit.
The variation was interpreted as due to motion of the pulsar toward and away from the Earth as one or more planet-sized objects orbit the pulsar, gravitationally tugging it to and fro.
He is one of many astronomers who hope for the discovery of a pulsar orbiting a black hole, since the tick of the pulsar's clock could perhaps be seen slowing in thrall of a black hole's mass.
The astronomers said the slowing of the pulsar's spin rate is negligible, which indicated that its initial rotation was only a few milliseconds faster.
Although the discovery was published only this week, many astronomers have heard the result and now consider that the life story of the pulsars has been clearly established.
The gamma-ray emissions do not come from particle beams at the poles of the pulsars, as is the case with radio pulsars, but instead arise far from the surfaces of the neutron stars.
The morphology is consistent with that observed recently with Chandra [Gaensler, B.M., van der Swaluw, E., Camilo, F., et al. The Mouse that soared: high resolution X-ray imaging of the pulsar-powered bow shock G359.23 0.82, ApJ 616, 383 402, 2004].
McWilliams noted that larger telescopes like the 305-meter Arecibo Telescope or the 500-meter FAST telescope in China can perform somewhat more precise timing of the pulsars in their line of view.
Most of the pulsars that spin faster than once per 20 milliseconds are part of a binary star system, but about 30% have no companions whatsoever, the scientists note.
