THE BLAZHKO EFFECT AND ADDITIONAL EXCITED MODES IN RR LYRAE STARS

ABSTRACT Recent photometric space missions, such as CoRoT and Kepler, revealed that many RR Lyrae stars pulsate-beyond their main radial pulsation mode-in low-amplitude modes. Space data seem to indicate a clear trend that, namely, overtone (RRc) stars and modulated fundamental (RRab) RR Lyrae stars...
