Orbital solutions and absolute elements of the eclipsing binary EE Aquarii.

WRONKA M.D., GOLD C., SOWELL J.R. and WILLIAMON R.M.

Abstract (from CDS):

EE Aqr is a 7.9 mag Algol variable with a 12 hr orbital period. The Wilson-Devinney program is used to simultaneously solve 11 previously published light curves together with two existing radial velocity curves. The resulting masses are M1= 2.24±0.13 M☉ and M2= 0.72±0.04 M☉, and the radii are R1= 1.76±0.03 R☉ and R2= 1.10±0.02 R ☉. The system has the lower-mass component completely filling its Roche lobe. Its distance from Hipparcos observations is 112±10 pc. An improved ephemeris is derived, and no deviations in the period over time were seen. Light and velocity curve parameters, orbital elements, and absolute dimensions are presented, plus a comparison is made with previous solutions.
