Pulsating Variable Star
A pulsating variable star is a type of star that undergoes periodic changes in luminosity due to expansion and contraction of its outer layers. These changes in luminosity are caused by variations in the star's internal structure and physical properties, such as temperature, pressure, and density. Pulsating variable stars are important objects of study in astronomy because they provide valuable information about the structure, evolution, and age of the universe. They are also used as standard candles for measuring distances to other galaxies. There are several types of pulsating variable stars, including Cepheids, RR Lyrae stars, and Mira variables.
