Abstract

We confirm 27 planets in 13 planetary systems by showing the existence of statistically significant anticorrelated transit timing variations, which demonstrates that the planet candidates are in the same system, and long-term dynamical stability, which places limits on the masses of the candidates–showing that they are planetary. All of these newly confirmed planetary systems have orbital periods that place them near first-order mean motion resonances (MMRs), including six systems near the 2: 1 MMR, five near 3: 2, and ...
