From the top down and back up again: star cluster structure from hierarchical star formation. [PDF]

Mon Not R Astron Soc, 2018
Young massive star clusters spanning ~104-108M⊙ in mass have been observed to have similar surface brightness profiles. We show that recent hydrodynamical simulations of star cluster formation have also produced star clusters with this structure.

Star Cluster Survival in Star Cluster Complexes under Extreme Residual Gas Expulsion [PDF]

, 2005
After the stars of a new, embedded star cluster have formed they blow the remaining gas out of the cluster. Especially winds of massive stars and definitely the on-set of the first supernovae can remove the residual gas from a cluster. This leads to a very violent mass-loss and leaves the cluster out of dynamical equilibrium.

The star formation history of the Large Magellanic Cloud as seen by star clusters and stars [PDF]

, 2010
The aim of this work is to test to what extent the star cluster population of a galaxy can be utilised to constrain or estimate the star formation history, with the Large Magellanic Cloud as our testbed. We follow two methods to extract information about the star formation rate from star clusters, either using only the most massive clusters ...

Evolution of Star Clusters near the Galactic Center: Fully Self-consistent N-body Simulations [PDF]

, 2007
We have performed fully self-consistent $N$-body simulations of star clusters near the Galactic center (GC). Such simulations have not been performed because it is difficult to perform fast and accurate simulations of such systems using conventional methods.

The influence of stellar-dynamical ejections and collisions on the relation between the maximum-star and star-cluster-mass [PDF]

, 2012
We perform the largest currently available set of direct N-body calculations of young star cluster models to study the dynamical influence, especially through the ejections of the most massive star in the cluster, on the current relation between the maximum-stellar-mass and the star-cluster-mass.

The Milky Way’s nuclear star cluster: Old, metal-rich, and cuspy [PDF]

Astronomy & Astrophysics, 2020
Context. The environment of Sagittarius A* (Sgr A*), the central black hole of the Milky Way, is the only place in the Universe where we can currently study the interaction between a nuclear star cluster and a massive black hole and infer the properties ...

GW190412 as a Third-generation Black Hole Merger from a Super Star Cluster [PDF]

Astrophysical Journal, 2020
We explore the possibility that GW190412, a binary black hole merger with a non-equal-mass ratio and significantly spinning primary, was formed through repeated black hole mergers in a dense super star cluster.

Investigating the effect of massive stars on the dynamical evolution of open clusters, using optimal and random sampling [PDF]

Iranian Journal of Physics Research, 2023
Massive OB stars have an important effect on the dynamical evolution of open star clusters. In the simulation of star clusters, the sampling method to determine the mass function of the cluster affects the number and mass of massive stars. Two methods of

The Perseus ALMA Chemistry Survey (PEACHES). II. Sulfur-bearing Species and Dust Polarization Revealing Shocked Regions in Protostars in the Perseus Molecular Cloud

The Astrophysical Journal, 2023
In protostellar cores, sulfur species are effective probes for the energetic environments, such as shocked regions. With the majority of sulfur depleted on dust grains, sulfur-bearing molecules could be liberated back to gas phase by shocks associated ...

Modeling Dense Star Clusters in the Milky Way and beyond with the Cluster Monte Carlo Code [PDF]

Astrophysical Journal Supplement Series, 2021
We describe the public release of the Cluster Monte Carlo (CMC) code, a parallel, star-by-star N-body code for modeling dense star clusters. CMC treats collisional stellar dynamics using Hénon’s method, where the cumulative effect of many two-body ...
