The RR Lyrae are members of an elite class of pulsating variables known as instability strippulsators. These stars, all confined to a narrow region of the Hertzsprung-Russell diagram, pulsate for the same reason: pulsations are driven by radiation being partially blocked from escaping the star, and the … See more Harvard College was a hive of variable star activity in the late 19th century.

WebWe report the discovery of an RR Lyr star that experienced a switching of its pulsation mode. OGLE-BLG-RRLYR-12245 was discovered as a double-mode RRd star based on observations conducted in the years 2001-2006 during the third phase of the Optical Gravitational Lensing Experiment (OGLE-III). The OGLE-IV observations carried out since 2010 reveal that this … WebRRLyr stars are short period ( 1 day) pulsators, horizontal branch stars that are in the Cepheid instability strip.

WebRR Lyr stars are named after the first member of their class to be studied in depth: RR Lyrae. This star was first noticed to vary in brightness by Wilhemina Fleming, who measured its properties on photograph plates taken as part of the Henry Draper project. Pickering et al., ApJ 13, 226 (1901) describe the star this way:
