A pulsar is a rapidly rotating neutron star. It produces flashing signals, either in the visible light spectrum, or the radio spectrum, or both. When radio pulsars were first discovered, the period of the signal was so precise, it was originally thought that they were radio signals from an alien source.
What else can I help you with?
How do you define a pulsar?
A pulsar is an extraterrestrial source emitting regular waves of electromagnetic radiation which is believed to be a rapidly rotating neutron star.
A rapidly rotating neutron star with an offset magnetic field that appears to blink to a distant observer is called a?
A pulsar
What is the difference between a galaxy and a pulsar?
A galaxy is a massive collection of stars, most orbiting around a supermassive black hole.A pulsar is a rapidly rotating neutron star that emits a beam of electronic radiation.See related questions.
What is a dense rotating star?
A pulsar.
Is a pulsar a neutron star?
Yes. A pulsar is a rapidly spinning neutron star.
A neutron star that rotates rapidly and emits light?
It's called a pulsar. However - ALL young neutron stars emit the said beam. It's only if that beam is detectable on Earth is it called a pulsar. So a Neutron Star and a Pulsar are the same thing. See related questions. but then again they are different.
Where does the energy of a pulsar came from?
The energy of a pulsar comes from its rotation as it slows down, converting rotational energy into radiation and particle acceleration. Pulsars are rapidly rotating neutron stars, and as they slow down over time, they emit electromagnetic radiation in the form of beams that sweep across our line of sight.
What type of energy does a pulsar emit?
A Pulsar is highly magnetised, rotating neutron star that emits a beam of electromagnetic radiation.
Where would you expect to find a pulsar?
A pulsar is a rapidly-spinning neutron star, the remains of a supernova explosion.
A pulsar requires that a neutron star 1rotate rapidly 2have a radius of at least 10Km 3have a stron magnetic field 4 rotate on an axis different from the axis of the magnetic field what is tru?
The true statement is: "A pulsar requires that a neutron star rotates rapidly." Pulsars are rapidly rotating neutron stars with strong magnetic fields, which emit beams of electromagnetic radiation along their magnetic poles, leading to their characteristic pulsed signals as they rotate. The other conditions mentioned are not essential for a neutron star to become a pulsar.
Why may there be more pulsars then we observe?
A "pulsar" is a rapidly rotating neutron star. The pulses are pulses of X-rays or gamma rays that are radiated continuously, but which are only detectable when the beam is pointed at the Earth.It seems likely that there are a great number of rotating neutron stars that do not happen to point at the Earth. They would not, therefore, be detectable.
What tool is used to observe a pulsar?
A pulsar is typically observed using radio telescopes, which can detect the regular pulses of radio waves emitted by the pulsar. These telescopes, such as the Arecibo Observatory or the Parkes Observatory, are equipped with sensitive receivers that can capture the faint signals from these rapidly rotating neutron stars. In addition to radio telescopes, optical and X-ray telescopes can also be used to study pulsars across different wavelengths.
