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.
What are one group of pulsating stars are called?

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.
Is Betelgeuse a pulsating star?
Yes, Betelgeuse is a pulsating star. It is a red supergiant star located in the constellation of Orion. Betelgeuse pulsates in size, changing in brightness over a period of about 420 days.
How old is mira the star?
Stars like Mira are not living beings with a specific age. Instead, Mira is a variable star, meaning its brightness changes over time due to its pulsating nature. Mira is estimated to be around 6 billion years old, which is about half the age of our Sun.
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?
No, RR Lyrae stars and RR Lyrae variables refer to the same type of pulsating variable stars. These stars are known for their regular variations in brightness due to pulsations in their outer layers.

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.

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.
Why are pulsating variable stars useful for finding distances to globular clusters?
Pulsating variable stars, like Cepheids and RR Lyrae stars, have a predictable relationship between their luminosity and period of pulsation. By observing the period of pulsation of these stars in globular clusters, astronomers can accurately determine their intrinsic brightness. By comparing this intrinsic brightness to the apparent brightness measured from Earth, astronomers can calculate the distance to the globular cluster using the inverse square law of brightness.
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.
What has the author Leon Campbell written?
Leon Campbell has written: 'The story of variable stars' -- subject(s): Stars, Variable, Variable stars
What are pulsating stars?
That refers to star that change their size, and therefore their brightness, in a repetitive pattern.
Is Betelgeuse a pulsating star?
Yes, Betelgeuse is a pulsating star. It is a red supergiant star located in the constellation of Orion. Betelgeuse pulsates in size, changing in brightness over a period of about 420 days.
