The Blue Lurker WOCS 14020: A Long-Period Post-Common-Envelope Binary in M67 Originating from a Merger in a Triple System
Emily M. Leiner, Natalie M. Gosnell, Aaron M. Geller +3
We present Hubble Space Telescope far-ultraviolet (FUV) spectra of a blue-lurkerwhite-dwarf (BL-WD) binary system in the 4 Gyr open cluster M67. We fit the FUV spectrum of the W…
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…
The Evolution of Substructure during Star Cluster Assembly
Edwin Laverde-Villarreal, Alison Sills, Claude Cournoyer-Cloutier +1
Star cluster formation and assembly occurs inside filamentary and turbulent molecular clouds, which imprints both spatial and kinematic substructure on the young cluster. In this p…
Dynamics of Star Cluster Formation: The Effects of Ongoing Star Formation and Stellar Feedback
Jeremy Karam, Michiko S. Fujii, Alison Sills
We perform a high resolution zoom-in simulation of star cluster assembly including the merger of two sub-clusters with initial conditions taken from previous large scale giant mole…
Massive Star Cluster Formation with Binaries. I. Evolution of Binary Populations
Claude Cournoyer-Cloutier, Alison Sills, William E. Harris +7
We study the evolution of populations of binary stars within massive cluster-forming regions. We simulate the formation of young massive star clusters within giant molecular clouds…
Binary Disruption and Ejected Stars from Hierarchical Star Cluster Assembly
Claude Cournoyer-Cloutier, Jeremy Karam, Alison Sills +2
We simulate mergers between star clusters embedded within their natal giant molecular cloud. We extract initial conditions from cloud-scale simulations of cluster formation and int…
