The pulsar is a rotating neutron star.

A neutron star is an extremely dense, tiny star, whose core is made up mainly of incredibly packed neutrons. A 7-miles neutron star may contain twice the mass of our sun (the density of a neutron star is typically 300 trillions times the density of sun). This mean that one cubic meter of a neutron star (a cube with about 3 feet side) would weigh about 500 trillions metric tons (one quadrillion US tons).
Gravity at the surface of a neutron star is about 200 billions times earth's gravity. That would men instantaeous and total flattening for us. Also, the gravitational force of a typical neutron star is such that if an object were to fall from a height of one meter, it would only take one microsecond to hit the surface of the neutron star, and would do so at around 2000 kilometers per second, or 7.2 million kilometers per hour.
The temperature of a neutron star is about one million kelvin degrees.

Neutron stars are the remnant of supernovae. A supernova may end up in a neutron star or a black hole, depending on various factors; a neutron star with mass > 5 M☉ (Greater than 5 times teh sun mass) usually becomes a black hole.

Neutron stars have been observed in their guise of pulsars.

A pulsar is a neutron star with a giant magnetic field which rotates. This gives rise to a stellar beacon, a focused  beam of light or electromagnetic radiation.
Only the pulsars whose beams are directed toward earth are visible to us. The beams is usually at an agle with the stars's rotation axis., this explains the fact that we see the beam each stella revolution.
Pulsars are also called stellar clocks because their recurrence (from millisecond to seconds) is extremely accurate. they rotate at various speeds.

An incredible condition is that of a binary system where one, or both the stars are neutron stars. The gravity field of a neutron star is solarge that it can suck up matter from nearby stars. Thsi is how Wikipedia describes such an astounding system

Quote
Disrupted recycled pulsar[edit]

When two massive stars are born close together from the same cloud of gas, they can form a binary system and orbit each other from birth. If those two stars are at least a few times as massive as our sun, their lives will both end in supernova explosions. The more massive star explodes first, leaving behind a neutron star. If the explosion does not kick the second star away, the binary system survives. The neutron star can now be visible as a radio pulsar, and it slowly loses energy and spins down. Later, the second star can swell up, allowing the neutron star to suck up its matter. The matter falling onto the neutron star spins it up and reduces its magnetic field. This is called “recycling” because it returns the neutron star to a quickly-spinning state. Finally, the second star also explodes in a supernova, producing another neutron star. If this second explosion also fails to disrupt the binary, a double neutron star binary is formed. Otherwise, the spun-up neutron star is left with no companion and becomes a “disrupted recycled pulsar”, spinning between a few and 50 times per second.[28]


Pulsars make up extremely accurate clock and are used also to this puprose:

Quote
Precise clocks[edit]

Generally, the regularity of pulsar emission does not rival the stability of atomic clocks.[32] For some millisecond pulsars, the regularity of pulsation is more precise than an atomic clock.[33] This stability allows millisecond pulsars to be used in establishing ephemeris time[34] or building pulsar clocks.[35]

Timing noise is the name for rotational irregularities observed in all pulsars. This timing noise is observable as random wandering in the pulse frequency or phase.[36] It is unknown whether timing noise is related to pulsar glitches.

A phenomen related to binary neutron stars is that of gravitational waves. Gravity spreads out in the space  like ripples on a Pond's surface.

Such waves are usually so small to be undetectable, if they were strong they would cause an effect similar to an earthquake.

They've been theorized by Einstein in 1916 .
In 1993, hulse & Taylor were awarded the nobel prize for giving evidence of gravitational waves generated by a binary pulsar system (one is a pulsar, the other si a neutron star which might also be a pulsar with the beam not focused on earth).

Below, an artistic depiction of a binary pulsar system like the Hulse-Taylor system. just A couple of immense stellar beacons.

Thsi is an artistic image of the spreading of gravitational waves (ripples thru the spacetime continuum) originated by a binary star system (the two bodies at the cenbter of the spiral).

Love u dear friend

Guess we are supposed to be apart of a binary star system... that has a 24 thousand year cycle. We should meet again as we have before. No one seems to have it down yet... which star that is that our Sun and solar system.... is dancing with.

Look at the background. Sometimes I see this cloudy dust of stars in the nite sky and I realize I am part of the great patience. Spirituality requires great patience -  patience with ourselves and patience  with others. Patience in our understanding and discovery into the great unknown

Steve, I too was ruminating on the sun binary system as proposed by sri Yukteswar and presently by teh Binary Research Insitute.

We must aknowledge that an eventual sun dual is still elusive, that is there si no proof yet. It might be one of the neutron stars above described, an incredibly tiny star, invisible, which has a mass Greater than the sun, so its gravity field influences the sun's orbit.

In modern astronomy the models are such that such an influence should be testable, but apparently it is not so.

So, we are not sure yet, accordin to present science,  if Sri Yukteswar intuition was exact and if our sun really has a dual, although the bianry research institute is actively busy in looking for signs.

Science is not errorless but today's astronomy is capable of incredible facts. I'll leave it at that.

http://www.binaryresearchinstitute.org/bri/research/calculations/100year.shtml

In the above link the BRI presents an alleged proof of the goodness fo fit which the bionary theory yields. I'm afraid I'm not so into astronomy to be a judge of that.

Also, the topic woudl deserve a thread on its own, the soalr system beign a binary system has been one recurring theory in astronomy. OK, I'm going to start it.
