The Possible Tidal Demise of Kepler's First Planetary System
Shreyas Vissapragada, Ashley Chontos, Michael Greklek-McKeon +6
We present evidence of tidally-driven inspiral in the Kepler-1658 (KOI-4) system, which consists of a giant planet (1.1, 5.9) orbiting an evolved host s…
TOI-1136 is a Young, Coplanar, Aligned Planetary System in a Pristine Resonant Chain
Fei Dai, Kento Masuda, Corey Beard +60
Convergent disk migration has long been suspected to be responsible for forming planetary systems with a chain of mean-motion resonances (MMR). Dynamical evolution over time could…
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…
The Upper Edge of the Neptune Desert Is Stable Against Photoevaporation
Shreyas Vissapragada, Heather A. Knutson, Michael Greklek-McKeon +9
Transit surveys indicate that there is a deficit of Neptune-sized planets on close-in orbits. If this ``Neptune desert' is entirely cleared out by atmospheric mass loss, then plane…
TESS Revisits WASP-12: Updated Orbital Decay Rate and Constraints on Atmospheric Variability
Ian Wong, Avi Shporer, Shreyas Vissapragada +4
After observing WASP-12 in the second year of the primary mission, the Transiting Exoplanet Survey Satellite (TESS) revisited the system in late 2021 during its extended mission. I…
