What are the variables of Lyra?

Lyra is home to several other famous variable stars. These include Beta Lyrae and RR Lyrae. Beta Lyrae, which serves as a prototype of the Beta Lyrae variables, is a close binary system that exhibits changes in brightness because the two components orbit each other and periodically block each other’s light. The eclipsing stars are so close that mass flows from one to the other and they are distorted by gravitational forces into an ellipsoidal shape. RR Lyrae is the prototype of the RR Lyra e variables, evolved giant stars that pulsate over a period of 0.2 to 1 day. These stars are commonly found in globular clusters and are used as standard candles to measure distance.
