Transferring Data from a Voronoi Mesh to an Adaptive Cartesian Grid in Pursuit of Self-consistent Top-down Star Formation
Sean C. Lewis, Brooke Polak, Mordecai-Mark Mac Low +5
Unstructured Voronoi mesh simulations offer many advantages for simulating self-gravitating gas dynamics on galactic scales. Adaptive mesh refinement (AMR) can be a powerful tool f…
Centrally concentrated star formation in young clusters
Adilkhan Assilkhan, Mordecai-Mark Mac Low, Brooke Polak +6
The study of star cluster evolution necessitates modeling how their density profiles develop from their natal gas distribution. Observational evidence indicates that many star clus…
Protostellar Jets in Star Cluster Formation and Evolution: I. Implementation and Initial Results
Sabrina M. Appel, Blakesley Burkhart, Mordecai-Mark Mac Low +8
Stars form in clusters from the gravitational collapse of giant molecular clouds, which is opposed by a variety of physical processes, including stellar feedback. The interplay bet…
Massive star cluster formation III. Early mass segregation during cluster assembly
Brooke Polak, Mordecai-Mark Mac Low, Ralf S. Klessen +6
Mass segregation is seen in many star clusters, but whether massive stars form in the center of a cluster or migrate there dynamically is still debated. N-body simulations have sho…
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…
Massive star cluster formation II. Runaway stars as fossils of sub-cluster mergers
Brooke Polak, Mordecai-Mark Mac Low, Ralf S. Klessen +6
Two main mechanisms have classically been proposed for the formation of runaway stars. In the binary supernova scenario (BSS), a massive star in a binary explodes as a supernova, e…
