Pulsating variable stars are intrinsic variables as their variation in brightness is due to a physical change within the star. ... The study of pulsating variables is of great importance to astronomers. Analysis of light curves provides vital information about the interior processes in stars.
Why are variable stars important?
Variable stars: future research
Research on variable stars is extremely important as it gives scientists information on star properties of mass, radius, temperature and luminosity, as well as information on the structure and composition of the star and how it has evolved.
Why do astronomers use variable stars?
The simple answer is that the intrinsic brightness of these variable stars is strongly tied to their period. ... So astronomers can predict the absolute magnitude (i.e., the mean intrinsic luminosity) of any given Cepheid by measuring the time it takes to rhythmically change its brightness.
