When the core of a massive star is compressed during a supernova explosion, then collapses into a neutron star, it retains most of its angular momentum.
Since it has only a tiny fraction of its original radius, a neutron star is formed with a very high rotational speed.
A pulsar is a highly magnetised, dense neutron star emitting a beam of electromagnetic radiation.

How do you use pulsate in a sentence?
The astronomer's observations proved that cephid variable stars would pulsate in a regular cycle
Pulsating variable stars are A-Binary stars B-Pulsars C-Novas D-Cephied Variables?
Cepheid Variables.
Are RR Lyrae stars and RR Lyrae variables different?
RR Lyrae variables are variable stars often used as standard candles. RR Lyrae are pulsating horizontal branch stars.
What kind of star is a pulsating star?
A pulsating star is a type of variable star that changes in brightness due to periodic expansions and contractions of its outer layers. These changes can be regular or irregular, and the star's size and temperature vary over time. Examples of pulsating stars include Cepheid variables and RR Lyrae stars.
Why did astronomers conclude that pulsars could not be pulsating stars?
Astronomers concluded that pulsars could not be pulsating stars because the regularity of their pulses was too precise and rapid to be explained by stellar pulsations. Additionally, pulsars were found to emit radiation across a wide range of wavelengths, which is not characteristic of pulsating stars. Further study revealed that pulsars are actually rapidly rotating neutron stars emitting beams of radiation that sweep across Earth as they rotate.
What does Cepheid mean?
A Cepheid is a member of a class of pulsating variable stars. The relationship between a Cepheid variable's luminosity and pulsation period is quite precise, securing Cepheids as viable standard candles and the foundation of the Extragalactic Distance Scale.
What are one group of pulsating stars are called?

Which star is a pulsating star?
There are two types of "pulsating" stars. 1. Pulsar 2. Quasar A pulsar is actually a neutron star that is rotating at a fast rate and is releasing a jet of X-rays. So, to a special telescope, it appears to be pulsating A quasar is similar to a pulsar, except for being a neutron star, it is a black hole.
Can pulsars be considered pulsating stars?
No, they are completely different. See related questions
Heavenly body with periodically changing luminosity?
Variable stars are those that have changing luminosities. There are two kinds of variable stars: intrinsic (where the variation is due to physical changes in the star), and extrinsic (where the variation is due to the eclipse of one star by another, or due to the effect of stellar rotation). They can be further divided into five different classes: the intrinsic pulsating, cataclysmic, eruptive variables, extrinsic eclipsing binary, and rotating stars.
What has the author Leon Campbell written?
Leon Campbell has written: 'The story of variable stars' -- subject(s): Stars, Variable, Variable stars
What type of star is torcular?
Torcular is a type of Mira variable star that exhibits pulsations and periodic changes in brightness. These stars are red giants that have expanded and are nearing the end of their life cycle, with their outer layers becoming unstable and pulsating.
