Title: A Study of AY Lyrae Authors: Danskin, K.; Mattei, J. A.
A study of the AAVSO data on the U Gem star AY Lyrae from 1935 to mid-1977 shows that it varies with a mean period of 23.7 days. It shows two types of outbursts: narrow-and-faint and wide-and-bright (supermaxima). A mean period of 205.5 days exists between supermaxima.
