A large sub-Neptune transiting the thick-disk M4V TOI-2406
R. D. Wells, B. V. Rackham, N. Schanche +71
Large sub-Neptunes are uncommon around the coolest stars in the Galaxy and are rarer still around those that are metal-poor. However, owing to the large planet-to-star radius ratio…
Six transiting planets and a chain of Laplace resonances in TOI-178
A. Leleu, Y. Alibert, N. C. Hara +152
Determining the architecture of multi-planetary systems is one of the cornerstones of understanding planet formation and evolution. Resonant systems are especially important as the…
Sensitivity Analyses of Exoplanet Occurrence Rates from Kepler and Gaia
Megan Shabram, Natalie Batalha, Susan E. Thompson +11
We infer the number of planets-per-star as a function of orbital period and planet size using archival data products with updated stellar properties from the Data R…
Kepler-62f: Kepler's First Small Planet in the Habitable Zone, but Is It Real?
William Borucki, Susan E. Thompson, Eric Agol +1
Kepler-62f is the first exoplanet small enough to plausibly have a rocky composition orbiting within the habitable zone (HZ) discovered by the Kepler Mission. The planet is 1.4 tim…
Re-Evaluating Small Long-Period Confirmed Planets From Kepler
Christopher J. Burke, F. Mullally, Susan E. Thompson +2
We re-examine the statistical confirmation of small long-period Kepler planet candidates in light of recent improvements in our understanding of the occurrence of systematic false…

The 0.8-4.5m broadband transmission spectra of TRAPPIST-1 planets
E. Ducrot, M. Sestovic, B. M. Morris +18
The TRAPPIST-1 planetary system represents an exceptional opportunity for the atmospheric characterization of temperate terrestrial exoplanets with the upcoming James Webb Space Te…
Kepler's Earth-like Planets Should Not Be Confirmed Without Independent Detection: The Case of Kepler-452b
Fergal Mullally, Susan E. Thompson, Jeffery L. Coughlin +2
We show that the claimed confirmed planet Kepler-452b (a.k.a. K07016.01, KIC 8311864) can not be confirmed using a purely statistical validation approach. Kepler detects many more…
Discovery of WASP-174b: Doppler tomography of a near-grazing transit
L. Y. Temple, C. Hellier, Y. Almleaky +23
We report the discovery and tomographic detection of WASP-174b, a planet with a near-grazing transit on a 4.23-d orbit around a = 11.9, F6V star with [Fe/H] = 0.09 0.09.…
Planetary Candidates Observed by Kepler. VIII. A Fully Automated Catalog With Measured Completeness and Reliability Based on Data Release 25
Susan E. Thompson, Jeffrey L. Coughlin, Kelsey Hoffman +58
We present the Kepler Object of Interest (KOI) catalog of transiting exoplanets based on searching four years of Kepler time series photometry (Data Release 25, Q1-Q17). The catalo…
Three's Company: An additional non-transiting super-Earth in the bright HD 3167 system, and masses for all three planets
Jessie L. Christiansen, Andrew Vanderburg, Jennifer Burt +55
HD 3167 is a bright (V = 8.9), nearby K0 star observed by the NASA K2 mission (EPIC 220383386), hosting two small, short-period transiting planets. Here we present the results of a…
Measuring Transit Signal Recovery in the Kepler Pipeline. III. Completeness of the Q1-Q17 DR24 Planet Candidate Catalogue, with Important Caveats for Occurrence Rate Calculations
Jessie L. Christiansen, Bruce D. Clarke, Christopher J. Burke +14
With each new version of the Kepler pipeline and resulting planet candidate catalogue, an updated measurement of the underlying planet population can only be recovered with an corr…
Detection of Potential Transit Signals in 17 Quarters of Kepler Data: Results of the Final Kepler Mission Transiting Planet Search (DR25)

We present results of the final Kepler Data Processing Pipeline search for transiting planet signals in the full 17-quarter primary mission data set. The search includes a total of…
Identifying False Alarms in the Kepler Planet Candidate Catalog
F. Mullally, Jeffery L. Coughlin, Susan E. Thompson +4
We present a new automated method to identify instrumental features masquerading as small, long period planets in the \kepler\ planet candidate catalog. These systematics, mistaken…
Planetary Candidates Observed by Kepler. VII. The First Fully Uniform Catalog Based on The Entire 48 Month Dataset (Q1-Q17 DR24)

We present the seventh Kepler planet candidate catalog, which is the first to be based on the entire, uniformly processed, 48 month Kepler dataset. This is the first fully automate…
A Machine Learning Technique to Identify Transit Shaped Signals
Susan E. Thompson, Fergal Mullally, Jeff Coughlin +4
We describe a new metric that uses machine learning to determine if a periodic signal found in a photometric time series appears to be shaped like the signature of a transiting exo…
