Period changes of OGLE contact binaries
Listed in IVOA Registry (Virtual Observatory)
Presented are results of determination of secular period changes for 569 contact binaries from the OGLE database with periods shorter than about one day and observations spanning 14 observing seasons.
Description
The statistically significant rates of secular changes found for 134 stars are distributed nearly symmetrically around zero with a half-width of the distribution equal to about 3.5x10^-7^d/yr. The remaining rates are confined within the error distribution with dispersion about 2.3x10^-7^d/yr.
The largest rates of period change that have been found are of the order of 5x10^-6^d/yr.
