摘要: We present the main results of a study observed internal structure constants, k2, for wide set eclipsing binaries. From analysis variations in relative positions eclipses and comparison with different theoretical models, we could deduce that discrepancy, previously reported by several authors between theory observations, is no longer supported. Moreover, strong correlation has been found evolution parameter k2 gravity at surface star, g.
