The origin of the most recently ejected OB runaway star from the R136 cluster
Simon Portegies Zwart, Michel Stoop, Lex Kaper +3
The solar-mass (\MSun) star-cluster R136 (NGC~2070) in the Tarantula Nebula in the Large Magellanic Cloud is the host of at least 55 massive stars ($M \apgt 10$\,\MS…
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…
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…
Two waves of massive stars running away from the young cluster R136
Mitchel Stoop, Alex de Koter, Lex Kaper +10
Massive stars are predominantly born in stellar associations or clusters. Their radiation fields, stellar winds, and supernovae strongly impact their local environment. In the firs…
Observational Bias and Young Massive Cluster Characterisation II. Can Gaia accurately observe young clusters and associations?
Anne S. M. Buckner, Tim Naylor, Clare L. Dobbs +2
Observations of clusters suffer from issues such as completeness, projection effects, resolving individual stars and extinction. As such, how accurate are measurements and conclusi…
Bringing Stellar Evolution & Feedback Together: Summary of proposals from the Lorentz Center Workshop, 2022
Sam Geen, Poojan Agrawal, Paul A. Crowther +34
Stars strongly impact their environment, and shape structures on all scales throughout the universe, in a process known as ``feedback''. Due to the complexity of both stellar evolu…
Using Molecular Gas Observations to Guide Initial Conditions for Star Cluster Simulations
Alison Sills, Steven Rieder, Anne S. M. Buckner +3
The earliest evolution of star clusters involves a phase of co-existence of both newly-formed stars, and the gas from which they are forming. Observations of the gas in such region…
The early evolution of young massive clusters: The kinematic history of NGC6611 / M16
Mitchel Stoop, Lex Kaper, Alex de Koter +3
In the first few Myr the massive stars dynamically interact, produce runaways and affect the initial binary population. Observing and interpreting the dynamics of young massive clu…
Observational Bias and Young Massive Cluster Characterisation I. 2D Perspective Effects
Anne S. M. Buckner, Kong You Liow, Clare L. Dobbs +2
Understanding the formation and evolution of high mass star clusters requires comparisons between theoretical and observational data to be made. Unfortunately, while the full phase…
Revisiting Common Envelope Evolution -- A New Semi-Analytic Model for N-body and Population Synthesis Codes
Alessandro Alberto Trani, Steven Rieder, Ataru Tanikawa +5
We present a novel way of modeling common envelope evolution in binary and few-body systems. We consider the common envelope inspiral as driven by a drag force with a power-law dep…
Grouped star formation: converting sink particles to stars in hydrodynamical simulations
K. Y. Liow, S. Rieder, C. L. Dobbs +1
Modelling star formation and resolving individual stars in numerical simulations of molecular clouds and galaxies is highly challenging. Simulations on very small scales can be suf…
The formation and early evolution of embedded star clusters in spiral galaxies
Steven Rieder, Clare Dobbs, Thomas Bending +2
We present Ekster, a new method for simulating star clusters from birth in a live galaxy simulation that combines the smoothed-particle hydrodynamics (SPH) method Phantom with the…
Two Directly Imaged, Wide-orbit Giant Planets around the Young, Solar Analog TYC 8998-760-1
Alexander J. Bohn, Matthew A. Kenworthy, Christian Ginski +9
Even though tens of directly imaged companions have been discovered in the past decades, the number of directly confirmed multiplanet systems is still small. Dynamical analysis of…
The Cosmic Ballet: spin and shape alignments of haloes in the cosmic web
Punyakoti Ganeshaiah Veena, Marius Cautun, Rien van de Weygaert +4
We investigate the alignment of haloes with the filaments of the cosmic web using an unprecedently large sample of dark matter haloes taken from the P-Millennium CDM cosmologica…
Dynamical evolution of stars and gas of young embedded stellar sub-clusters
Alison Sills, Steven Rieder, Jennifer Scora +2
We present simulations of the dynamical evolution of young embedded star clusters. Our initial conditions are directly derived from X-ray, infrared, and radio observations of local…
