On the pulsational-orbital-period relation of eclipsing binaries with δ-Sct components.

ZHANG X.B., LUO C.Q. and FU J.N.

Abstract (from CDS):

We have deduced a theoretical relation between the pulsation and orbital-periods of pulsating stars in close binaries based on their Roche lobe filling. It appears to be of a simple linear form, with the slope as a function of the pulsation constant, the mass ratio, and the filling factor for an individual system. Testing the data of 69 known eclipsing binaries containing δ-Sct-type components yields an empirical slope of 0.020±0.006 for the Ppul-Porb relation. We have further derived the upper limit of the Ppul/Porb ratio for the δ-Sct stars in eclipsing binaries with a value of 0.09 ±0.02. This value could serve as a criterion to distinguish whether or not a pulsator in an eclipsing binary pulsates in the p-mode. Applying the deduced Ppul-Porbrelation, we have computed the dominant pulsation constants for 37 δ-Sct stars in eclipsing systems with definite photometric solutions. These ranged between 0.008 and 0.033 days with a mean value of about 0.014 days, indicating that δ-Sct stars in eclipsing binaries mostly pulsate in the fourth or fifth overtones.
