First photometric study of the eclipsing binary PS Persei

الأصل · EN

The CCD photometric observations of the eclipsing binary PS Persei (PS Per) were obtained on two consecutive days in 2009. The 2003 version Wilson-Devinney code was used to analyze the first complete light curves in V and R bands. It is found that PS Per is a short-period Algol-type binary with the less massive component accurately filling its inner critical Roche lobe. The mass ratio of q=0.518 and the orbital inclination of i=89.∘86 are obtained. On the other hand, based on all available times of primary light minimum including two new ones, the orbital period has been improved.
