V473 Lyrae
V473 Lyrae is a variable star in the constellation Lyra. It is an unusual Classical Cepheid variable with a range of 5.99 to 6.35 and a period of 1.49078 days. It is unique in that it is the only known Cepheid in the Milky Way to undergo periodic phase and amplitude changes, analogous to the Blazhko effect in RR Lyrae stars.〔 At 1.5 days, its period was the shortest known for a classical Cepheid at the time of its discovery.〔 ==References==
