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 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 semiregular variable star so it is classed as a pulsating star.
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?
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.
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.
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.
What are pulsating stars?
That refers to star that change their size, and therefore their brightness, in a repetitive pattern.
Why are pulsating variable stars useful for finding distances to globular clusters?
It really depends on the type of star, but for certain star types, there is a relationship between the period and the absolute brightness, so if the period is observed, the absolute brightness can be deduced. Yes. It seems like this question is about the Cepheid variables.
Is Betelgeuse a pulsating star?
Yes: Betelgeuse is a semiregular variable star so it is classed as a pulsating star.
