TESS time of eclipse of 15 eclipsing binaries

The change in the argument of periastron of eclipsing binaries, that is, the apsidal motion caused by classical and relativistic effects, can be measured from variations in the...

食双星（eclipsing binaries）的近心点幅角（argument of periastron）变化，即由经典效应与相对论效应共同引发的近心点运动（apsidal motion），可通过……中的变化进行测量。
