Formation of Super-Earths and Mini-Neptunes from Rings of Planetesimals
The Astrophysical Journal LettersThe solar system's planetary architecture has been proposed to be consistent with the terrestrial and giant planets forming from material rings at ∼1 au and ∼5 au, respectively.

Predicting the Dominant Formation Mechanism of Multiplanetary Systems
The Astrophysical Journal LettersMost, if not all, Sun-like stars host one or more planets, making multiplanetary systems commonplace in our Galaxy. We utilize hundreds of multiplanet simulations to explore the origin of such systems, focusing on their orbital architecture.

Planet–Planet Scattering and Von Zeipel–Lidov–Kozai Migration—The Dynamical History of HAT-P-11
The Astrophysical JournalThe two planets of the HAT-P-11 system represent fascinating dynamical puzzles due to their significant eccentricities and orbital misalignments. In particular, HAT-P-11 b is in a close-in orbit in which tides should have circularized well within the age

The PFS View of TOI-677 b: A Spin–Orbit Aligned Warm Jupiter in a Dynamically Hot System
The Astronomical JournalTOI-677 b is part of an emerging class of “tidally detached” gas giants ( a / R _⋆ ≳ 11) that exhibit large orbital eccentricities and yet low stellar obliquities. Such sources pose a challenge for models of giant planet formation, which must account for

Relative Occurrence Rate between Hot and Cold Jupiters as an Indicator to Probe Planet Migration
The Astrophysical JournalWe propose a second-order statistic parameter ε , the relative occurrence rate between hot Jupiters (HJs) and cold Jupiters (CJs) ( ε = η _HJ / η _CJ ), to probe the migration of gas giants. Since the planet occurrence rate is the combined outcome of the
