Transit Timing Variations

(variations in the timing of the transits of exoplanets and binaries)

Transit Timing Variations (TTVs) of Binary Stars and Extra Solar Planets are easily measured by clock and reveal information about such star systems. They can reveal the presence of additional stars and planets and can also reveal masses, in particular the ratio of masses.

Transits varying in an anti-correlated manner, i.e., one occurring sooner when the other occurs later, provides additional evidence of an additional planet because this is typical when two planets are affecting each other's orbits.
