Abstract:
Stromgren b,y photometry of the detached A-type eclipsing binary EG
Serpentis was obtained. Combined with the radial velocity curves in
Popper [PASP, 98, 1312 (1986)], it was used to determine anew the
system's parameters using the Wilson-Devinney code. The age of the
system is derived from a comparison with the Bertelli et al. [A&AS, 85,
845 (1990)] isochrones. Within the accuracy limits, the results are in
accordance with expectations.
