Pulsation of IU Per from the Ground-based and `Integral' Photometry

Gális, R.; Kundra, E.; Hric, L.

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 s…
