Peculiar double-periodic pulsation in RR Lyrae stars of the OGLE collection: II. Short-period stars with a dominant radial fundamental mode
Abstract: We report the discovery of a new group of double-periodic stars in the OGLE Galactic bulge photometry. In 38 stars identified as fundamental-mode RR Lyrae and four classified as first-overtone RR Lyrae, we detected an additional shorter periodicity.
