Pulsation of IU Per from the Ground-based and ‘Integral’ Photometry

IU Per is an eclipsing semi-detached binary with a pulsating component. Using our own ground-based, as well as INTEGRAL satellite photometric observations in the B and V passbands, we derived geometrical and physical parameters of this system. We detected the short-term variations of IU Per in the residuals of brightness after the subtraction of synthetic light curves. Analysis of these residuals enabled us to characterize and localize the source of short-term variations as the pulsations of the primary component typical to δ Scuti-type stars.

Keywords: stars: binaries: eclipsing; stars: oscillations; stars: variables: δ Scuti; stars: individual (IU Per)
