J/AJ/105/2291 The eclipsing binary EG Ser (Trudel+ 1993) ================================================================================ The eclipsing binary EG Serpentis TRUDEL J.-L., FERNIE J.D., MOCHNACKI S. =1993AJ....105.2291T ================================================================================ ADC_Keywords: Binaries, eclipsing; Photometry 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.
