A statistical method for the determination of the rate of changes of period for eclipsing binaries.
Abstract
Summary. A statistical treatment for the quantitative analysis of period changes AP for eclipsing binaries is given. The method can be applied to a series of measurements of minima times. It allows one to determine the rate of period change AP/At and also gives a test of the reality of sudden period changes of contact binaries. The method can only be applied to the best observed stars. Examples are given for SW Lac and 44i Boo. Key words: eclipsing binaries - contact binaries - period changes of double stars
