Bailey types A classification of RR Lyrae stars according to the shape and amplitude of their light curves, devised by Solon Bailey in 1899. Types a, b, and c were defined originally, but types a and b are usually combined today. RRa stars show a sharp rise to maximum followed by a slow fall to minimum; RRc stars have a smaller amplitude and a rise and fall of equal length.
