Survey reveals dichotomy in orbital alignment of small planets in binary systems, suggesting different dynamical histories.
Key Points
The alignment of small planets in binary systems displays a dichotomy, with two distinctive distributions observed.
Analysis of 26 binary systems showed strong preference for mixture models, indicating differing dynamical histories for planet-binary systems.
Identified approximately 12 TOIs with potential planetary-mass companions, contributing to the understanding of stellar multiplicity and planet formation.
The misaligned population of binary systems occurs when stellar periastron distances exceed 40 AU, implying a significant role of distance in orbital evolution.
