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 information on masses, in particular ratios of masses, actual masses (or compared to the host star) likely to require modeling and computation.

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