About article:
AO Ser is an eclipsing binary of the Algol type. We aim to present a
new model of AO Ser and to justify the presence and the mode of
pulsations of its primary component. We achieved these objectives by
modelling our original U,B,V,RC,IC light-curves.
Pulsations were investigated by means of the periodic analysis. In this way
we determined fundamental (L,R,T) parameters of the binary
components, their masses and the distance
d=671+3-4pc to AO Ser. Our mass-ratio
q=0.396 of the components is not consistent with previous estimates.
We also argue that a suspected third component is not present in this
system. Finally, we confirmed pulsations of the primary component and
derived its more accurate period Ppuls=0.040 d. The
primary pulsates in the first non-radial mode l=3.
