You know that there are many unidentified natural objects in space. I think you have read my previous articles too. From there, even though I had told you about some newly founded things. I can remember that also I told you about another neutron star before. Then today I am going to tell you about another neutron star that had found recently. I guess you would like to know about this new neutron star. Before that actually, we have to appreciate the works by the scientists. If they don’t want alive we couldn’t know the details about the incidents, things and others about the outer space. But thanks to those scientists we can get much knowledge about outer space though we are on the earth. After paying gratitude towards the scientists, now we can start our topic.
You know that today I am talking about a neutron star. Before moving to it, you have to find out what is a neutron star. Then we will see what that is??
What is a neutron star??
Neutron stars have a radius of about 10 kilometres, and mass is about 1.4 solar mass. Actually, the neutron star is a collapsed core of a giant star. Before collapsing it has a weight of approximately about 10-29 solar masses in other than that this is a result of a supernova. Later we will see the supernova explosion.
In other than that this is consistent with the neutrons. We will see some more about the neutrons now.
There are subatomic particles inside matter. Neutrons are subatomic particles. Electrons and protons are some other subatomic particles. These particles are known as neutrons because they are neutral. They haven’t any electrical charge as well as that they are more massive than the protons.
Then there are some unique features of the neutron star. You can see them from the follows.
The mass of a neutron star is about 2.2 solar mass. The lowest weight is about 1.1 solar mass. Approximately temperature is about 1011 to 1012kelvin. There is a classification of neutron stars according to their weight and the heat. In the Type I neutron stars with low mass and cooling rates. Then in the type II neutron stars with higher mass and cooling rates. In other than that, the type III neutrons with higher mass and with higher cooling rates. The density of a neutron star is about 3.7 ×10 17 to 5.9×10 17 kg/m3. Neutron stars are so dense that one teaspoon of matter inside the neutron star is about 5.5×1012 of mass. That is equivalent to 900 times about the pyramid of Giza. The gravitational power of these neutron stars is as one teaspoon is about 1.1×1025 N weight.
In other than that the pressure of a neutron star about 3.2×10 31 to 1.6×10 34 Pa. This pressure increases from the inner crust to the centre. The magnetic field is powerful about 104 to 1011 Tesla. There is another name for neutron stars because of this powerful magnetic field. It is the magnetars. Magnetars have a range between 10 8 and 10 11 teslas. I have finished telling you about the neutron star. Now you know the idea about a neutron star. Then we can talk about the mission.
This mission is planned by NASA. We will later talk about the neutron star. This neutron star found within the Pisces constellation. As per the measurements of the astronomy, it is 16 miles wide. The mass of it approximately about 1.3 times as the sun. NASA constructed a map by using the available details. This map was created by the supercomputers by NASA. It is a very difficult task if we do that from a regular personal computer, it will take more time. But NASA wants to make new plans that including more new neutron stars.
That is about the project. Now we will see about that neutron star.
The j0030-0451 neutron star
This is a category of a pulsar star. This is a neutron star that emits beams of electromagnetic radiation. That is through magnetic poles. This can be visible to us when the electromagnetic ray falls toward the earth. This makes the astronomers very easy. This is used to confirm the existence of gravitational radiation.
The first neutron star was identified in 2016. It is by the AR Scorpio. This is a pulsar in which the compact object is a white dwarf instead of a neutron star.
With the discovery of this star, astronomers have got a better chance to study the neutron stars. Those pulsars are included with the first radio pulsar, the brightest radio pulsar, the first Xray pulsar, the first accelerating millisecond x-ray pulsar. These above are some more important details about the pulsar neutron stars.
The pulsars orbiting within the curved space-time around Sgr A. Then the pulses would be affected by special and general-relativistic Doppler shifts. The pulsars in orbital periods less than about ten years would need to be discovered.
You know that there is various electromagnetic radiation emitted by the pulsar stars. That pulsars emit radiation by the interstellar medium. That is before the reach to earth. The lower frequency radio waves travel through the medium slower than, the higher frequency radio waves. That is because of the dispersive nature of the interstellar plasma. The delay of the arrival of the pulses at a range of frequencies measured by the dispersion measure of the pulses. This is a measure is the total column density of the overall column density.
Pulsar maps have two such as pioneer Plaque and Voyager golden. Their position is relative to the 14 pulsars. The location means the position when considered with the sun. That pulsar stars are usually emitting very regular radio waves. Then pulsar positioning creates the spacecraft navigation system or in the satellite navigation. Often, this pulsar emission does not rival the stability of atomic clocks.
There are some types of pulsars. Rotation powered pulsars. Accretion powered pulsars and magnetars are those types. The rotation powered pulsars loss of the rotational energy gives the power to the star. Then the accretion powered pulses use the gravitational potential energy and the accreted matter to gain the control. Then the other one is the magnets. Magnetars are the pulses that use the decay of an extremely strong magnetic field provides the electromagnetic power.
Then I have reached the end of my article. I told you a neutron star. Now you know this is a type of a pulsar star. There will more neutron stars found in the future. I would like you to tell you if there are some more new alerts.
