Delta Scuti Variables
Delta Scuti Variables are a type of pulsating star that exhibit changes in brightness due to periodic expansions and contractions. These stars are typically found in the Hertzsprung-Russell diagram as intermediate-mass stars, often located in the instability strip. Their pulsation periods range from a few hours to a few days.
The variability in brightness is caused by stellar pulsation, which is influenced by the star's temperature and composition. Delta Scuti Variables are important for astronomers as they help in understanding stellar evolution and the internal structure of stars. Their study contributes to the broader field of asteroseismology.
