Systematic mischaracterization of exoplanetary system dynamical histories from a model degeneracy near mean-motion resonance

27 Aug 2018 Boisvert John H. Nelson Benjamin E. Steffen Jason H.

There is a degeneracy in the radial velocity exoplanet signal between a single planet on an eccentric orbit and a two-planet system with a period ratio of 2:1. This degeneracy could lead to misunderstandings of the dynamical histories of planetary systems as well as measurements of planetary abundances if the correct architecture is not established...
