A Photometric Analysis of the Binary System KO Aquilae
We report photometric uvbyoi observations of the variable KO Aqlobtained during the summer of 1993. One time of primary minima wasobserved, and improved quadratic and linear ephemerides were calculated.Eclipse timings of KO Aql, spanning over a sixty year interval, showthat the system is undergoing a period increase of 1.7 (+- 0.1) X 10^-8days/cycle. Analysis of our photometry with the new Wilson eclipsingbinary computer program indicates that the mass ratio of the system is0.29 and that the secondary star is cooler than the previouslydetermined G0 spectral type. The masses and radii of the two componentsare also estimated. (SECTION: Stars)
