Binary imposters: Mergers in massive hierarchical triple stars
F. Kummer, G. Simion, S. Toonen +1
Massive stars are often born in triples, where gravitational dynamics and stellar interactions play a crucial role in shaping their evolution. One such pathway includes the merger…
A high fraction of close massive binary stars at low metallicity
H. Sana, T. Shenar, J. Bodensteiner +74
At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…
Massive Interacting Binaries Enhance Feedback in Star-Forming Regions
Claude Cournoyer-Cloutier, Eric P. Andersson, Sabrina M. Appel +9
We present a new framework to incorporate feedback from massive interacting binaries in simulations of star cluster formation. Our new feedback model adds binary stellar evolution…
Detailed Simulations of Massive Hierarchical Triple Star Systems - Exploring the impact of the stellar physics on the evolutionary pathways of massive hierarchical triple systems
Luca Sciarini, Sylvia Ekström, Floris Kummer +4
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…
Binarity at LOw Metallicity (BLOeM): Enhanced multiplicity of early B-type dwarfs and giants at
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…
