EB Ford, D Ragozzine, JF Rowe… - The Astrophysical …, 2012 - iopscience.iop.org
Transit timing variations provide a powerful tool for confirming and characterizing transiting
planets, as well as detecting non-transiting planets. We report the results of an updated …

Following up the Kepler field: Masses of Targets for transit timing and atmospheric characterization

D Jontof-Hutter, A Wolfgang, EB Ford… - The Astronomical …, 2021 - iopscience.iop.org
We identify a set of planetary systems observed by Kepler that merit transit-timing variation
