The aim of this work is to study the gravity and the effective temperature distribution on the outer equipotential surface of a contact binary. In particular, the lines of constant g, (the iso-g curves), are computed and plotted on the outer surface

The O−C diagram of the contact eclipsing binary AB And was reanalysed, using data obtained up to now. It was thus found that the real period variations, presented by the P(E)−P e function, have changed; both P mod and its amplitude continue to de

The O−C diagram of U Oph, based on photoelectric and charge-coupled device data on the times of minimum light, was analysed. The traditional analysis method was used because of the clear sinusoidal shape of the O−C diagram (with a constant period

We present the results from a sample of early type binaries, for which the surface gravity of their primary components was computed using two different ways. From a comparison of the derived gravity values, is found that the existing difference betwe

Two light curve solutions for the close eclipsing binary II UMa, using Hipparcos data, are presented. The analysis was made using the PHOEBE program. The first solution was derived adopting the spectroscopic value q = 0.172 while the presence of thir

The influence of the gravity darkening effect in the formation of a non iso‐thermal photosphere on close binary stars is presented. Furthermore, a theoretical model that describes thermal differences on the stars’ surfaces, based on the temperatu

The orbital period variations of the eclipsing binary BX And are examined analysing its (O-C) diagram 1) with the standard method, in which the minima times are fitted by the quadratic ephemeris combined with an assumed light-time effect, and 2) with
