θ1 Ori C as a Medieval Bully: A Possible Very Recent Ejection in the Trapezium.

MAIZ APELLANIZ J., PANTALEONI GONZALEZ M. and BARBA R.H.

Abstract (from CDS):

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