Amplitude variability or close frequencies in pulsating stars – the δ Scuti star FG Vir.
BREGER M. and PAMYATNYKH A.A.
Abstract (from CDS):
If we examine these three close frequency pairs together with other (usually more widely separated) close frequencies in FG Vir, 18 pairs of frequencies with separations closer than 0.10 cycle/d have been detected. It is shown that the majority of the pairs occur near the theoretically expected frequencies of radial modes. Mode identifications are available for only a few modes: the only detected radial mode at 12.15 cycle/d is part of a close pair.
It is shown that accidental agreements between the frequencies of excited modes can be ruled out because of the large number of detected close frequency doublets.
