In theory, pulsars could remain intact at speeds as high as 1,000 to 3,000 revolutions per second. |
|
Most millisecond pulsars hover around the 300 revolutions per second mark, and the fastest spinning pulsar ever detected clocked in at 641 rps. |
|
However, the relationship between spin-down rate and magneto-dipole losses is not as straightforward for pulsars that also emit X-rays. |
|
The laboratory demonstration is related to puzzling glitches observed by astronomers in the otherwise smooth, rapid rotation of pulsars. |
|
That pulsars are part of a binary system is indicated by Doppler shifts in the pulse period and the change in arrival time of the pulse. |
|

|
The Universe has its own heavenly sounds, such as pulsars, planetary magnetospheres and solar winds. |
|
All in all he quintupled the number of known pulsars in that particular sector of the sky. |
|
Today some 10 neutron-star-neutron-star binaries have been discovered, and radio astronomy has accumulated a spectacular database of more than 1500 pulsars. |
|
Australian radio astronomers assisted Apollo moon missions and were first to identify the existence of radio galaxies, and numerous pulsars and quasars. |
|
By monitoring their pulses to the millisecond, pulsars could rival the most accurate atomic clock. |
|
They do not come much littler than pulsars, which despite weighing about as much as the sun are a mere ten kilometres in diameter. |
|
If pulsars are responsible, theory predicts that the positron fraction should decline steadily at energies above this value. |
|
The pulsars, of which more than one thousand are known today, are interpreted as being neutron stars in rotation. |
|
For that reason, such objects are called pulsars, and they have provided our best data about neutron stars. |
|
Some researchers have already patented pulsars as interstellar navigational beacons. |
|
That was discovered in 1965. Dr Gold was also on the money with his explanation of pulsars. |
|
Collaboration is maintained with a number of radio-astronomy groups observing pulsars and analysing pulsar data. |
|
|
Other research subjects are pulsars, future clocks in space and atom interferometry. |
|
Even though pulsars emit light in the visible spectrum, they are far too small and far away for us to detect any of this visible light. |
|
New pulsars are constantly being discovered, and some of these are in systems that can be used to advantage for precision timekeeping: ongoing pulsar surveys make any list of preferred pulsars dynamic. |
|
There have been awards for pulsars and radio astronomy. |
|
Multipath scattering in the interstellar medium causes a broadening of pulses of radio emission from pulsars, which decreases approximately as the fourth power of the frequency. |
|
Even so, the statistics of pulsars are likely to be observationally biased, since signals from pulsars at great distances in the Galaxy become distorted by ionized regions of interstellar space. |
|
Fourteen of the lines represent the distances to pulsars and include binary numbers giving the periods of the pulsing radiation from these objects. |
|
Starting March 1998, the efficacity of the system was validated by the successful detection of two pulsars known to be present in the test observations. |
|
Rolling on themselves like cosmic metronomes, and loosing energy in their double dance, pulsars are at the crossroad of the topics of the colloquia: time, matter and energy. |
|
In a few month only, thanks to its higher sensitivity, tens of gamma-ray pulsars were discovered, out of which a third was totally unknown in any other wavelength domains. |
|
At the same time, another team has located nine new gamma-ray pulsars in Fermi data, using improved analytical techniques. |
|
The speed at which these pulsars rotate enables researchers to measure the timing of the radio waves' arrival at Earth with high accuracy. |
|
This Report examines the possibility of using high-precision timing radio observations of millisecond pulsars for constructing and maintaining new pulsar-based astronomical time scales. |
|
Their work on neutron star pulses, the sudden changes in the spin rates of pulsars, and the observations the researchers make through x-rays and radio waves is producing information about the interiors of these unusual stars. |
|
Her team also found a missing link between pulsars and magnetars-another type of neutron star characterized by an ultra-strong magnetic field-clarifying the poorly understood relationship between these distant relatives. |
|
These millisecond pulsars have been spun up and rejuvenated by accreting matter from a companion star. |
|
Coauthor of a paper on the galactic distribution of pulsars. |
|
Dr Petit concluded by emphasizing the need for more long-term, low-noise observations of millisecond pulsars which have good rotational stability. |
|

|
It is widely accepted now that they are old recycled pulsars that have been re-accelerated, by grabing matter and angular momentum to a close and less evolved companion star within a binary system. |
|
|
This process was helped by the discovery of pulsars in 1967, which, by 1969, were shown to be rapidly rotating neutron stars. |
|
Also John Macintyre, pioneer of radiology and Jocelyn Bell Burnell who discovered radio pulsars. |
|
A wide variety of objects are observable at radio wavelengths, including supernovae, interstellar gas, pulsars, and active galactic nuclei. |
|
He picked up the coveted Golden Spurtle just two weeks ago after submitting his PhD thesis on pulsars. |
|
There, he had used radio waves to probe the secrets of pulsars, the spinning, magnetized neutron stars that emit bursts of radiation with clocklike regularity. |
|
Pulsars and quasars may turn out to be commonplace in comparison to the exotic astrophysical events that gravity wave astronomy reveals. |
