Abstract
This paper examines the observational evidence for the detection of gravity modes in δ Scuti stars, which are p-mode pulsators. Low-order gravity modes have also been found in at least one star (FG Vir). Some reports of gravity modes may be due to systematic errors in the absolute magnitude calibrations for slowly rotating stars. Furthermore, many detected low frequencies are not high-order gravity modes, but linear combinations, f i -f j , of the main pulsation modes. Other low frequencies are caused by a close binary companion leading to tidal deformation as well as tidally excited gravity modes.
