Description

The study of compact multi-planet systems provides us with unique insight into planet formation and evolution processes, particularly resonant systems that retain the architectures of early formation stages prior to destabilizing events. Within this framework, we will present a novel analysis of a two-planet system consisting of a confirmed planet and candidate companion in a possible mean-motion resonance. The study will focus on refining the architecture of the system using a photo-dynamical analysis of Kepler photometric data. The aim of this analysis is to confirm the candidate planet as well as to determine the resonant state of the system, and the planetary masses, in order to further improve our understanding of multi-planet systems.
