A 150 Msun candidate runaway star.

Mathieu Renzo’s investigation of what is probably the most massive runaway star currently known. Using Gaia and Hubble Space Telescope data he tries to determine the origin of this extreme star, which has likely been ejected by the very young star cluster R136. The cluster is famous for harboring several of these monster stars as shown in earlier work. Now published in MNRAS.
