OBS

Among the yellow and reddish variable stars, around types G and K, which do not conform to the principal patterns, 40 or more form a sort of connecting link between the cepheids and the red variables. They are known as RV Tauri stars after one of their members. Their variations in light in a semiregular manner are ascribed at least partly to pulsations.
