muutujaitega

Muutujaitega, also known as variable stars, are stars whose luminosity changes over time due to intrinsic variations. These variations can be periodic or non-periodic, and they can be caused by a variety of mechanisms, including pulsation, rotation, eclipses, and mass transfer in binary systems. Variable stars are important in astronomy for several reasons. They can be used to measure distances in the universe, as their intrinsic brightness can be related to their observed brightness. They also provide insights into the physical properties of stars, such as their mass, radius, and age. Variable stars are classified into several types based on their light curves and the mechanisms that cause their variations. Some of the most well-known types include Cepheid variables, RR Lyrae variables, and eclipsing binaries. The study of variable stars is a active field of research in astronomy, with new discoveries and insights being made all the time.
