Recent observations estimate that 30% of early B and O-type stars are found in triple systems. So far, the evolution of triple star systems has mainly been modeled using fast stell…
A systematic method to identify runaways from star clusters produced from single-binary interactions: A case study of M67
A. Herrera-Urquieta, N. Leigh, J. Pinto +9
One hypothesis for runaway stars (RSs) is that they are ejected from star clusters with high velocities relative to the cluster center-of-mass motion. There are two competing mecha…

J. I. Villaseñor, H. Sana, L. Mahy +32
Early B-type stars ( M) are frequently in multiple systems, as evidenced by spectroscopic campaigns in the Milky Way (MW) and the Large Magellanic Cloud (LMC). Pr…
Binarity at LOw Metallicity (BLOeM): The multiplicity properties and evolution of BAF-type supergiants
L. R. Patrick, D. J. Lennon, F. Najarro +36
Given the uncertain evolutionary status of blue supergiant stars, their multiplicity properties hold vital clues to better understand their origin and evolution. As part of The Bin…
Binarity at Low Metallicity (BLOeM) -- Multiplicity properties of Oe and Be stars
J. Bodensteiner, T. Shenar, H. Sana +40
Rapidly rotating classical OBe stars have been proposed as the products of binary interactions, and the fraction of Be stars with compact companions implies that at least some are.…
BH-BH mergers with & without EM counterpart: A model for stable tertiary mass transfer in hierarchical triple systems
F. Kummer, S. Toonen, A. Dorozsmai +2
Triple stars are prevalent within the population of observed stars. Their evolution, compared to binaries, is notably more complex, influenced by unique dynamical, tidal, and mass…
Massive stellar triples on the edge: A numerical study of the evolution and final outcomes of destabilized massive triples
