$\theta^1$ Ori C as a medieval bully: a possible very recent ejection in the Trapezium

Solar and Stellar Astrophysics 2021-10-18 v1 Astrophysics of Galaxies

Abstract

We use Gaia EDR3 astrometry to propose that a dynamical interaction between the multiple system θ1\theta^1 Ori C and θ1\theta^1 Ori F ejected the latter as a walkaway star ~1100 years ago (without deceleration) or somewhat later (with a more likely deceleration included). It is unclear whether the final 3-D velocity of θ1\theta^1 Ori F will be large enough to escape the Orion nebula cluster.
