| Abstract: |
The paper presents results of the Fourier analysis of 12 RR Lyrae stars with periods within the double-mode pulsation range in the globular cluster M15. Approximately 400 photographic plates of M15 were taken between 1937 and 1966 at the Konkoly Observatory. Evidence in support of the reality of the variation in the amplitude of the fundamental mode oscillation is presented for the variables V51 and V26. |
