RR Lyrae stars are members of a class of VARIABLE STAR whose variations in light, radius and temperature are known to be caused by self-sustained radial pulsations of giant A stars with masses between 0.5 and 0.8 solar masses, mean radii of 5 times the radius of the Sun and absolute magnitudes at mean light of ˜+0.5. The amplitudes of their light curves range between 0.2 and 1.8 magnitudes in...
