Supernovae and their associated binary disruptions can eject companion stars outward, contributing significantly to the observed population of runaway stars in the galaxy.

The analysis

The retrieved papers include studies confirming that when massive stars undergo supernovae in binary systems, the sudden disruption or mass loss frequently ejects companion stars into space as runaway stars (the binary supernova scenario). Papers [2] and [10] provide direct evidence and modeling of this outward ejection process.

Stellar ejection velocities from the binary supernova scenario: A comparison across population synthesis codes
