The Formation and Early Dynamical Evolution of Bound Stellar Systems

TLDR
In this paper, the results of numerical N-body calculations which simulate the dynamical evolution of young clusters as they emerge from molecular clouds have been presented, and the combination of these parameters which result in the production of bound stellar groups after the gas not used in star formation is completely dispersed.
Abstract
We present the results of numerical N-body calculations which simulate the dynamical evolution of young clusters as they emerge from molecular clouds. We follow the evolution of initially virialized stellar systems of 50 and, in some cases, 100 stars from the point in time immediately after the stars have formed in a cloud until a time long after all the residual star-forming gas has been dispersed from the system. By varying the star formation efficiency and the gas dispersal time for each model, we determined the combination of these parameters which result in the production of bound stellar groups after the gas not used in star formation is completely dispersed.

Gas expulsion and the destruction of massive young clusters

TL;DR: In this paper, the authors examined the luminosity and dynamical mass estimates for young massive stellar clusters and showed that 50% of these clusters are likely to be destroyed within a few 10s Myr of their formation.

The Genesis of Super Star Clusters as Self-Gravitating HII Regions

TL;DR: In this paper, the effects of ionization, radiation pressure and main sequence winds from massive stars on self-gravitating, clumpy molecular clouds, thereby modeling the formation and pre-supernova feedback of massive star clusters were examined.

Turbulent, Molecular Clouds Regulated by Radiation Feedback

TL;DR: In this paper, a series of simulations employing the Hyperion radiation hydrodynamics solver was conducted to investigate how radiation forces influence realistic clouds, considering the regime that is optically thick to ultraviolet and optically thin to infrared radiation.

Open clusters in a dispersing molecular cloud

TL;DR: In this paper, the authors used N-body simulations to find that most star clusters survive for more than 40 Myr even when the mass loss rate is high, which is the main reason for high infant mortality in star clusters.

Embedded Clusters in Molecular Clouds

TL;DR: The first extensive catalog of galactic embedded clusters is compiled, finding that the embedded cluster birthrate exceeds that of visible open clusters by an order of magnitude or more indicating a high infant mortality rate for protocluster systems.

Young Massive Star Clusters

TL;DR: A review of the current state of the art in observations and dynamical modeling of young massive star clusters can be found in this paper, where the authors focus on star clusters younger than 100$ Myr, more than a few current crossing times old, and more massive than 10^4$Msun.

Gravitational N-Body Simulations

TL;DR: The N-body problem has been studied in a wide range of applications, e.g., prediction-corrector methods, neighbor treatments, tree codes, chain procedures, and chain procedures with GRAPE as mentioned in this paper.

A Universal Formation Mechanism for Open and Globular Clusters in Turbulent Gas

TL;DR: In this article, a universal mechanism for cluster formation in all epochs and environments is found to be consistent with the properties and locations of young and old globular clusters, open clusters and unbound associations, and interstellar clouds.
