pulsars造句

Studies of pulsars, neutron stars, and quark stars are reviewed.

Typically, millisecond pulsars are around a billion years old.

Sky surveys have identified about 1800 pulsars within the Milky Way, most of which emit pulsing radio signals that rise and fall as the pulsars spin.

There may be a real physical cause for dispersion of the pulsars out of the plane.

Supernovae remnants can leave behind pulsars or spinning neutron stars that may produce gravitational waves.

Some pulsars keep time better than the Earth's most accurate clocks.

Astronomers keep discovering new noisemakers in space: colliding black holes, glitching pulsars, gamma ray bursts.

Thus, a significant fraction of pulsars are being missed in the surveys.

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

Neutron stars and quark stars are currently two kinds of speculated subjects when one is modeling observed pulsars.

It is possible that an average pulsar time scale PTens may be deduced through along-term stability algorithm using precision timing data from more millisecond pulsars.

The search for pulsars has been one of ALFA's main tasks, carried out by an international, open group of astronomers, the ALFA Pulsar Consortium.

But the find was part of a major international search designed to look for and study pulsars across the sky - and that search is far from over.

As pulsars are very dense, the matter should exist in the form different from normal matter, so nuclear matter-extension of nucleus, is good candidate.

Most known pulsars were only found by "integrating" their signal: superposing a large number of pulses in a coordinated way to make the actual "pulse" signal stand out from the "static".

Is the current understanding correct or is there a surplus of either pulsars in binaries or those that were kicked out of the pairs through asymmetries in the stars' final blow ups?

Such sources are believed to be either quark stars or neutron stars, and a subclass of these are already observed by conventional means as pulsars or X-ray emitting celestial objects.
