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.
"About two-thirds of all variable stars appear to be pulsating. In the 1930s astronomer Arthur Stanley Eddington showed that the mathematical equations that describe the interior of a star may lead to instabilities that cause a star to pulsate. The most common type of instability is related to oscillations in the degree of ionization in outer, convective layers of the star.
"Suppose the star is in the swelling phase. Its outer layers expand, causing them to cool. Because of the decreasing temperature the degree of ionization also decreases. This makes the gas more transparent, and thus makes it easier for the star to radiate its energy. This in turn will make the star start to contract. As the gas is thereby compressed, it is heated and the degree of ionization again increases. This makes the gas more opaque, and radiation temporarily becomes captured in the gas. This heats the gas further, leading it to expand once again. Thus a cycle of expansion and compression (swelling and shrinking) is maintained."
If you mean is it a variable star where it's apparent brightness fluctuates: then yes it is.
If you mean, is Antares a pulsar: then it is not.
The first pulsar was viwed apon on November 28, 1967 by Jocelyn Bell Burnell and Antony Hewish.
The name of that pulsar is: LGM-1.

Yes: Betelgeuse is a semiregular variable star so it is classed as a pulsating star.

A variable star (or pulsating star) is a star that an earth observer sees as changing in luminosity over time. This variation in brightness may be something the star is "doing itself" because of changes in its nucleosynthetic processes, or it may be due to the passage of dust clouds or the like between the star and the observer. Wikipedia has more information, and you'll find a link to their post below.

Pulsating Theory According to this theory, the universe is supposed to be expanding and contracting alternately i.e. pulsating. At present, the universe is expanding. According to pulsating theory, it is possible that at a certain time, the expansion of the universe may be stopped by the gravitational pull and the may contract again. After it has been contracted to a certain size, explosion again occurs and the universe will start expanding. The alternate expansion and contraction of the universe give rise to pulsating universe.
Yes: Betelgeuse is a semiregular variable star so it is classed as a pulsating star.
no.
Cooler and Dimmer
That refers to star that change their size, and therefore their brightness, in a repetitive pattern.
3 words pulsating radio star
My heart is pulsating.
The beat was pulsating
The root word for pulsating is pulsate.
Pulsating xenid was created in 1834.
It was a pulsating match and everyone really enjoyed it.
I have the same problem. I have spark, fuel presure, dont start. But if i use starting fluid it will star.
pulsating red light.
