Kepler-50: Two Planets in Close Resonance Perturbed by a Non-transiting Planet
Daniel Jontof-Hutter, Jason F. Rowe, Jack J. Lissauer +1
Kepler-50 has two transiting planets close to the 6:5 commensurability. We analyze transit times measured from Kepler data with dynamical fits. We attribute the residual signal to…
Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903
Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173
Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…
A Fourth Planet in the Kepler-51 System Revealed by Transit Timing Variations

Gaussian Processes and Nested Sampling Applied to Kepler's Small Long-period Exoplanet Candidates
Michael R. B. Matesic, Jason F. Rowe, John H. Livingston +3
There are more than 5000 confirmed and validated planets beyond the solar system to date, more than half of which were discovered by NASA's Kepler mission. The catalog of Kepler's…
Updated Catalog of Kepler Planet Candidates: Focus on Accuracy and Orbital Periods
Jack J. Lissauer, Jason F. Rowe, Daniel Jontof-Hutter +5
We present a new catalog of Kepler planet candidates that prioritizes accuracy of planetary dispositions and properties over uniformity. This catalog contains 4376 transiting plane…
The Kepler Giant Planet Search. I: A Decade of Kepler Planet-host Radial Velocities from W. M. Keck Observatory
Lauren M. Weiss, Howard Isaacson, Andrew W. Howard +17
Despite the importance of Jupiter and Saturn to Earth's formation and habitability, there has not yet been a comprehensive observational study of how giant exoplanets correlate wit…
A Decade of Linear and Circular Polarimetry with the POLISH2 Polarimeter
Sloane J. Wiktorowicz, Agnieszka Słowikowska, Larissa A. Nofi +15
The POLISH2 optical polarimeter has been in operation at the Lick Observatory 3-m Shane telescope since 2011, and it was commissioned at the Gemini North 8-m in 2016. This instrume…
Refining the Masses and Radii of the Star Kepler-33 and its Five Transiting Planets
James Sikora, Jason Rowe, Daniel Jontof-Hutter +1
Kepler-33 hosts five validated transiting planets ranging in period from 5 to 41 days. The planets are in nearly co-planar orbits and exhibit remarkably similar (appropriately scal…
Constraining the Densities of the Three Kepler-289 Planets with Transit Timing Variations
Michael Greklek-McKeon, Heather A. Knutson, Shreyas Vissapragada +4
Kepler-289 is a three-planet system containing two sub-Neptunes and one cool giant planet orbiting a young, Sun-like star. All three planets exhibit transit timing variations (TTVs…
TESS Observations of Kepler systems with Transit Timing Variations
Daniel Jontof-Hutter, Paul A. Dalba, John H. Livingston
We identify targets in the Kepler field that may be characterized by transit timing variations (TTVs) and are detectable by the Transiting Exoplanet Survey Satellite (TESS). Despit…
Following up the Kepler field: Masses of Targets for transit timing and atmospheric characterization
Daniel Jontof-Hutter, Angie Wolfgang, Eric B. Ford +3
We identify a set of planetary systems observed by Kepler that merit transit timing variation (TTV) analysis given the orbital periods of transiting planets, the uncertainties for…
A Featureless Infrared Transmission Spectrum for the Super-Puff Planet Kepler-79d
Yayaati Chachan, Daniel Jontof-Hutter, Heather A. Knutson +12
Extremely low density planets ('super-puffs') are a small but intriguing subset of the transiting planet population. With masses in the super-Earth range ( M) and…
Predicting the long-term stability of compact multiplanet systems
Daniel Tamayo, Miles Cranmer, Samuel Hadden +11
We combine analytical understanding of resonant dynamics in two-planet systems with machine learning techniques to train a model capable of robustly classifying stability in compac…
TESS discovery of a super-Earth and three sub-Neptunes hosted by the bright, Sun-like star HD 108236
Tansu Daylan, Kartik Pingle, Jasmine Wright +59
We report the discovery and validation of four extrasolar planets hosted by the nearby, bright, Sun-like (G3V) star HD~108236 using data from the Transiting Exoplanet Survey Satell…
The Compositional Diversity of Low-Mass Exoplanets
Daniel Jontof-Hutter
Low-mass planets have an extraordinarily diverse range of bulk compositions, from primarily rocky worlds to those with deep gaseous atmospheres. As techniques for measuring the mas…

Erik A. Petigura, John Livingston, Konstantin Batygin +11
K2-19b and c were among the first planets discovered by NASA's K2 mission and together stand in stark contrast with the physical and orbital properties of the solar system planets.…
