Early studies of apsidal motion in binary stars showed a marked discrepancy between observational results and theoretical expectation (Schwarzschild, 1958; Kopal, 1965). Improvements in theory (Petty, 1973; Odell, 1974; Stothers, 1974) have led to much closer agreement. However, recent observational results (Giménez & García-Pelayo, 1982; Monet, 1980) have provided much more data with which to test theoretical results.
