Distant TNO Inclinations as a Constraint on Primordial Cluster Perturbations in the Presence of Planet Nine

Avni Bansal, Ian Brunton, Konstantin Batygin +2

The Sun was almost certainly born in a stellar cluster, implying some degree of external forcing from neighboring stars during the Solar System's infancy. Published estimates of th…
