Scientific paper

1998 UBV photometry of short period eclipsing binary ST Aquarii have been presented. The photometric solution obtained from light curve analysis by the method of differential corrections indicates that the system can be classified as a near contact binary. Derived value for the ratio of radii left( {k = {left< {r_c } rightrangle }/{left< {r_h rightrangle }} \cong 0.67} right) shows that both components cannot be considered to be Main-Sequence, but they are probably evolved from M.S.
