Star cluster dynamics [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2009
Dynamical evolution plays a key role in shaping the current properties of star clusters and star cluster systems. A detailed understanding of the effects of evolutionary processes is essential to be able to disentangle the properties which result from ...

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.

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

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

, 2008
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 ...

Star cluster ecology IVa: Dissection of an open star cluster---photometry [PDF]

Monthly Notices of the Royal Astronomical Society, 2000
The evolution of star clusters is studied using N-body simulations in which the evolution of single stars and binaries are taken self-consistently into account.

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 ...

The Birth of Massive Stars and Star Clusters [PDF]

, 2005
In the present-day universe, it appears that most, and perhaps all, massive stars are born in star clusters. It also appears that all star clusters contain stars drawn from an approximately universal initial mass function, so that almost all rich young star clusters contain massive stars.

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

Nuclear star clusters [PDF]

The Astronomy and Astrophysics Review, 2020
AbstractWe review the current knowledge about nuclear star clusters (NSCs), the spectacularly dense and massive assemblies of stars found at the centers of most galaxies. Recent observational and theoretical works suggest that many NSC properties, including their masses, densities, and stellar populations, vary with the properties of their host ...

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 ...
