Orbital Solutions and Absolute Elements of the Eclipsing Binary EE Aquarii EE Aqr is a 7.9 mag Algol variable with a 12 hr orbital period. TheWilson-Devinney program is used to simultaneously solve 11 previouslypublished light curves together with two existing radial velocitycurves. The resulting masses are M 1 = 2.24 ± 0.13 Msun and M 2 = 0.72 ± 0.04 M sun,and the radii are R 1 = 1.76 ± 0.03 R sunand R 2 = 1.10 ± 0.02 R sun. The system hasthe lower-mass component completely filling its Roche lobe. Its distancefrom Hipparcos observations is 112 ± 10 pc. An improved ephemerisis derived, and no deviations in the period over time were seen. Lightand velocity curve parameters, orbital elements, and absolute dimensionsare presented, plus a comparison is made with previous solutions.
