pulsar

But it's been mostly cannibalized by its pulsar companion, and is now just a shadow of its former self.

The mass of the Crab Pulsar is not too different from that of the sun.

In the nebula's very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town.

Apriori we do not know the exact distance, spin frequency, and orbital parameters of the radio pulsar that might be hidden in a data set.

In the nebula's very center lies a pulsar: aneutron star as massive as the Sun but with only the size of a smalltown.

How can we tell the difference between the sound of the Sun and the sound of a pulsar?

A pulsar is not a normal star, but a dense, rapidly spinning remnant of a supernova explosion.

As the pulsar rotates, this beam sweeps the sky in the same way that a light house beam sweeps around the horrizon.

LEDs then began to appear as indicator lights in calculators and watches, including the famous digital Pulsar watch.

In theory, the first step toward producing a millisecond pulsar is the formation of a neutron star when a massive star goes supernova.

Astronomers have tracked the movement of a pulsar, making the first direct measurement of its impressive speed.

The position of the pulsar at the upper right end of the tail is seen by mousing over the image.

One of the neutron stars is a pulsar; it emits radio pulses at regular intervals as it spins 45 times per second.

Moreover, we get a set of pulsar binaries with known sky positions and orbital parameters.

Such "pulsar glitches" likely result from brief interactions between the neutron star's solid crust and superfluid interior.

That the observed X-rays might originate from residual internal heat of this 50 million year-old pulsar was also ruled out.

The fast-spinning star is a pulsar, a super dense chunk of matter left over when a massive star explodes, then collapses in on itself.

XMM-Newton has, for the first time, detected signals from both stars of a binary pulsar system in X-rays, unveiling a scientific goldmine.

This star is clearly not the pulsar as it is about equally bright on both exposures.

The pulses appear to speed up and slow down slightly as the pulsar swings around its companion.

There is one other possible explanation for what scientists have seen: They could be watching the birth instead of a pulsar wind nebula.

A millisecond pulsar is a super compact neutron star, whose spin is highly accelerated by mass transferred from a companion star.

First of all the reason of the pulsar dispersion and several popular de-dispersion algorithms are introduced.

And when this picture was made with Chandra X-ray Observatory, they discovered immediately that the pulsar also produces a jet.

Explore the Doppler effect in a binary pulsar system by downloading the "Pulsating Science" 3D visualisation software.

Or you could hop in a starship and cruise 4, 000 light years over to a dead star called pulsar J1719-1438.

A pulsar is a type of stellar corpse that emits powerful beams of radio waves from its poles.

Such features are known as pulsar wind nebulas.

The next step is to test whether there is a radio pulsar present in that data set on that (or a similar) orbit.

The pulsar super-resolution TOA algorithm based on stationary wavelet transform and fractional Fourier transform is proposed.

The comparisons between the frequency stabilities for atomic time and pulsar time are presented.

In these data sets, our pulsar search aims to find binaries with orbital periods longer than eleven minutes.

And this object, this pulsar in the Crab Nebula is radiating copious amounts of x-rays, of gamma rays.

First of all, coordinate systems and time systems are introduced, and phase-time model of pulsar is analyzed.

Long? term stability of the ensemble pulsar time is obviously better than that of atomic time.

And Chandra made a picture very recently of the Crab Nebula, of the pulsar, and that's what I want to show you now.

Finally, the minimum distance classifier is used to classify pulsar signals.

As of 2007, three extrasolar planets have been confirmed in orbit around this pulsar.

An X-ray binary system has been formed, and the neutron star has made the crucial second step toward becoming a millisecond pulsar.

The limited sensitivity of present pulsar surveys and the greater frequency drift make the more distant pulsars difficult to observe.

So the Crab Pulsar alone generates about 150, 000 times more power than the sun.

All these worlds cannot support life as we know it, permanently bathed as they are in the pulsar's high-energy radiation.

Numerical simulation shows that the REKF is more accurate than the EKF for spacecraft navigation in the presence of pulsar's position error.

The Vela pulsar is the brightest persistent source in the gamma-ray sky.

This is when I concentrated on pulsars and built a large machine to do realtime processing of pulsar radio signals, right at the telescope.

in contrast , a pulsar emits a lot of its radiation in radio wave.

A pulsar is a celestial object that emits light in short burst.

Besides, the X-ray pulses detected from pulsar B were too strong.

called a Disrupted Recycled Pulsar.

Binary star systems containing a pulsar and an accretion disk occur beginning at about 14: 30.

With the results from this pulsar search, we improve our understanding of how many binaries with neutron stars may be out there in total.

In brilliant blue, this is the pulsar wind nebula of the Crab Nebula in the constellation of Taurus.

The researchers determined that the precession of the pulsar's orbital axis advances by 4. 77 degrees per year, plus or minus 0. 66 degrees.

We know the period of the pulsar to a very high degree of accuracy.

The pulsar signal is a kind of typical nonstationary random signal which SNR (Signal to Noise Ratio) is very low.

There is an object which we call the Crab Pulsar.

The Crab Pulsar rotates about 30 times each second.

Gerald Ford wore a hi-tech electronic Pulsar that cost $2, 000.

for example, collect each of the Mickey Mouse, Donald Duck & Goofy Game Pieces to win the Nissan Pulsar Q.

However, gravitational radiation has been indirectly observed as an energy loss over time in binary pulsar systems such as PSR 1913 16.

It is also a circumbinary planet, orbiting around a binary system composed of the pulsar PSR B1620-26 A and the white dwarf WD B1620-26.

We use a three dimensional pulsar magnetosphere model to study the geometry of outer- magnetospheric gaps.

And so here you have the data on the Crab Pulsar.

The Crab pulsar, the best-known example of a bright pulsar wind nebula, is about 950 years old.
