Stars end their lives forming beautiful nebulae. On the way towards illuminating nebulae, many of them enter an unstable stage of life where the star’s surface pulsates, producing a rhythmic pattern of light that can be observed by astronomers. An example of this are RV Tauri Variable Stars. These stars are particularly important in understanding the end of a stars' life. My goal is to create a new list of RV Tauri Variable Stars from a list of potential candidates.
