摘要：

Results of the photometric analysis by means of the Wilson-Devinney method, combined with an empirical mass-radius relation for LC IV stars support the hypothesis that GX Gem is a well detached evolved system of subgiant stars. The solution is consistent with the known spectroscopic parameters obtained by Popper (1996) and the photometric data of Lacy (2002a).
