ASTEP confirmation of a pair of long-period Jupiter-sized planets with extremely low densities transiting TOI-791

Georgina Dransfield, Antoine C. Petit, Amaury H. M. J. Triaud +45

Gas giant planets with periods orbiting Sun-like stars are a relatively uncommon outcome of planetary formation, and key questions about the nature and form…

Uncovering the Rapidly Evolving Orbits of the Dynamic TOI-201 System

Ismael Mireles, Solène Ulmer-Moll, Donald Liveoak +47

Studying planetary interactions in exoplanet systems informs theories of planet formation and evolution, providing essential context for understanding our own solar system. We comb…

Close-in compact super-Earth systems emerging from resonant chains: slow destabilization by unseen remnants of formation

Max Goldberg, Antoine C. Petit

Planet formation simulations consistently predict compact systems of numerous small planets in chains of mean motion resonances formed by planet-disk interaction, but transiting pl…

The Dynamical History of the Kepler-221 Planet System

Tian Yi, Chris W. Ormel, Shuo Huang +1

Kepler-221 is a G-type star hosting four planets. In this system, planets b, c, and e are in (or near) a 6:3:1 three-body resonance even though the planets' period ratios show sign…

From Stability to Instability: Characterizing the Eccentricities of Multi-planet Systems in the California Kepler Survey as a Means of Studying Stability

Matthew J. Doty, Lauren M. Weiss, Matthias Y. He +1

Understanding the stability of exoplanet systems is crucial for constraining planetary formation and evolution theories. We use the machine-learning stability indicator, SPOCK, to…

Long-term stability and dynamical spacing of compact planetary systems

Antoine C. Petit

Exoplanet detection surveys revealed the existence of numerous multi-planetary systems packed close to their stability limit. In this proceeding, we review the mechanism driving th…

The Solar System could have formed in a low-viscosity disc: A dynamical study from giant planet migration to the Nice model

Philippine Griveaud, Aurélien Crida, Antoine C. Petit +2

In the context of low-viscosity protoplanetary discs (PPDs), the formation scenarios of the Solar System should be revisited. In particular, the Jupiter-Saturn pair has been shown…

Dynamical Evolution of Planetary Systems

Antoine C. Petit, Gabriele Pichierri, Max Goldberg +1

Planetary systems can evolve dynamically even after the planets themselves have fully formed, and there is circumstantial evidence that most planetary systems become unstable after…

Dynamical evolution of planetary systems

Alessandro Morbidelli

The apparent regularity of the motion of the giant planets of our solar system suggested for decades that said planets formed onto orbits similar to the current ones and that nothi…
