Refined parameters, formation, and dynamical stability of the wild exoplanet system K2-312=HD 80653
L. Naponiello, E. Poretti, K. Rice +24
The architecture of planetary systems hosting ultra-short-period (USP) planets is a key diagnostic for understanding formation and migration scenarios. The presence of outer giant…
Understanding eccentric temperate giants: an in-depth study of the architecture and stellar obliquity of the TOI-2134 system
Federica Rescigno, Manu Stalport, Ancy Anna John +28
We revisit the TOI-2134 planetary system with three new high-cadence TESS sectors and 98 more spectra. This new analysis confirms the two orbiting planets by simultaneously modelli…
The Architecture of the 14 Herculis System Suggests Primordial Ejection of a Massive Planet
Tiger Lu, Sarah C. Millholland, Malena Rice +6
The 14 Herculis system hosts two super-Jupiters on eccentric, significantly misaligned orbits. This orbital architecture represents a dynamical puzzle that demands explanation. In…
A Massive Hot-Jupiter Companion that Disfavors Giant Planet Formation Beyond the Water-Ice Line
Eritas Yang, Tiger Lu, Daniel A. Yahalomi +1
We report evidence for a brown-dwarf companion with mass in the KELT-20 system, in which an ultra-hot Jupiter transits an A2-type star. The companion's p…
A Coordinate System for Dynamical Instabilities in Hierarchical Systems in REBOUND
Tiger Lu, Garett Brown
We implement coordinates suitable for studying wide binary systems in TRACE, a hybrid integrator in the widely used open-source N-body integration package REBOUND. This is a regime…
Observational and Dynamical Constraints on an Unseen Outer Perturber in the GJ 436 Hot Neptune System
Haedam Im, Tiger Lu, Malena Rice +3
Hot Neptunes in the sub-Jovian desert offer unique insights into planetary system evolution, retaining signatures of dynamical processes that shaped their present-day architectures…
