Accounting for Transit Timing Detectability: Biases in Planetary Radius and Orbital Period
Skylar D'Angiolillo, Daniel Fabrycky, Mariah G. MacDonald
Transit Timing Variations (TTVs) are deviations from the time an observer would expect to see an exoplanet transit its host star. In multi-planetary systems, significant TTVs may i…
Updated Masses for the Gas Giants in the Eight-Planet Kepler-90 System Via Transit-Timing Variation and Radial Velocity Observations
David E. Shaw, Lauren M. Weiss, Eric Agol +28
The eight-planet Kepler-90 system exhibits the greatest multiplicity of planets found to date. All eight planets are transiting and were discovered in photometry from the NASA Kepl…
Validating the Orbital Periods of the Coolest TESS Exoplanet Candidates
Dillon Bass, Daniel Fabrycky
When an exoplanet passes in front of its host star, the resulting eclipse causes an observable decrease in stellar flux, and when multiple such transits are detected, the orbital p…
Transit Timing and Duration Variations for the Discovery and Characterization of Exoplanets in the TESS era
Eric Agol, Daniel Fabrycky
Transiting exoplanets in multi-planet systems have non-Keplerian orbits which can cause the times and durations of transits to vary. The theory and observations of transit timing v…
