A Study of the Spectroscopic Variability of Select RV Tauri... Charles Kurgatt , Donald K. Walter , Steve Howell
... RV Tauri and Semi-Regular stars are examples of variable stars, a star that is unable to maintain a steady apparent brightness. These changes in brightness may have many causes such as eclipses, stellar rotation, and pulsation. The two types studied here vary in brightness due to pulsations in the p ...
