Abstract:
A detailed study of the eclipsing binary system AW UMa is presented. A new period (P = 0.ᵈ4387317) is given. Period changes in different portions of the O-C diagram, based on new period, have been estimated. The total change in period (ΔP) ranges from 2.2х10¯⁷ to 2.8х10¯⁶d, which is normal for AW UMa systems. Two distinct linear trends of period are visible in the O-C diagram. A third trend shows a new change in the period behaviour, which is yet to be confirmed.
