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…

FROST-CLUSTERS -- II. Massive stars, binaries and triples boost supermassive black hole seed formation in assembling star clusters
Antti Rantala, Natalia Lahén, Thorsten Naab +2
Observations and high-resolution hydrodynamical simulations indicate that massive star clusters form through a complex hierarchical assembly. We use simulations including post-Newt…

Mergers all the way down: stellar collisions and kinematics of a dense hierarchically forming massive star cluster in a dwarf starburst
Natalia Lahén, Thorsten Naab, Antti Rantala +1
Recent observations indicate that the progenitors of globular clusters (GCs) at high redshifts had high average stellar surface densities above $10^5\, \mathrm{M}_\odot\, \mathrm{p…
