The triple star zeta Aquarii.
Abstract
The accumulated data base of photographic plates of Zeta Aquarii are analyzed to verify the presence of a third companion and determine its physical and dynamic characteristics. A table of the relative orbital positions and residuals measured from 1781-1982 is provided. The masses of the stars are calculated to be 1.5, 0.4 and 1.5 solar mass, with the smallest star being fainter than 8 mag. A set of ephemerides is generated for 1982-2004.
