Transit Timing Variations (TTVs) can provide useful information for systems
observed by transit, by putting constraints on the masses and eccentricities of
the observed planets, or even constrain the existence of non-transiting
companions. However, TTVs can also prevent the detection of small planets in
transit surveys, or bias the recovered planetary and transit parameters. Here
we show that Kepler-1972 c, initially the "not transit-like" false positive
KOI-3184.02, is an Earth-sized planet whose orbit is perturbed by Kepler-1972 b
(initially KOI-3184.01). …
