The VLT-FLAMES Tarantula Survey Observational evidence for two distinct populations of massive runaway stars in 30 Doradus (2022)
Journal Article
Observational evidence for two distinct populations of massive runaway stars in 30 Doradus. Astronomy & Astrophysics, https://doi.org/10.1051/0004-6361/202244677

Context. The origin of massive runaway stars is an important unsolved problem in astrophysics. Two main scenarios have been proposed, namely: dynamical ejection or release from a binary at the first core collapse. However, their relative contribution...
