Scientific paper

We obtained radial velocity measurement for seven members of the rare
class of eclipsing δ Scuti systems. We investigate the effects of
a close companion on the pulsational frequencies of the δ Scuti
star. We find an orbital period cutoff of ~4 days where the δ
Scuti star no longer fits conventional pulsational models.
