Code associated to the Renzo et al. 2019a. In this paper we used Gaia DR2 data to test the kinematics of a >150Mo star, VFTS682, and found it was plausibly ejected from the core of the R136 cluster, despite being that massive. This possibly makes it the third >100Mo star ejected from this cluster, together with VFTS72 and VFTS16 Lennon et al. 2018, and the most massive runaway star known to date.
