Space astrometry of the very massive ∼150 M⊙ candidate runaway star VFTS682

Code associated to the Renzo et al. 2019a. In this paper we used Gaia DR2 data to test the kinematics of a >150M_o 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 >100M_o star ejected from this cluster, together with VFTS72 and VFTS16 Lennon et al. 2018, and the most massive runaway star known to date.

See the paper (Renzo et al. 2019a, MNRASL,482,L102-L106) for more information.
