AbstractThe overtone and multi-mode RR Lyrae stars in the globular cluster M3 are studied (...) 70% of the 52 overtone variables observed show some kind of multi-periodicity (...). A signal at the 0.587 frequency ratio to the fundamental-mode frequency is detected in the double-mode star, V13, which may be identified as the second radial overtone mode. If this mode identification is correct, than V13 is the first RR Lyrae star showing triple-mode pulsation of the first three radial modes. (...) The changes of the Blazhko and double-mode properties of the stars are also reviewed using the recent and archive photometric data.
