Self-consistent simulations of star cluster formation from gas clouds under the influence of galaxy-scale tidal fields

TL;DR

This paper demonstrates the first self-consistent simulation of star cluster formation from gas clouds within a galaxy-scale tidal field, reproducing observed cluster properties and providing insights into their evolution.

Contribution

It introduces a novel simulation approach that models star cluster formation within a galaxy potential, capturing long-term dynamical evolution and structural features.

Findings

Successfully formed a bound star cluster from a giant molecular cloud

Reproduced observed density profiles and structural characteristics of star clusters

Demonstrated the impact of galaxy-scale tidal fields on cluster formation and evolution

Abstract

We present the first results of a project aimed at following the formation and long-term dynamical evolution of star clusters within the potential of a host galaxy. Here we focus on a model evolved within a simplified potential representing the Large Magellanic Cloud. This demonstrates for the first time the self-consistent formation of a bound star cluster from a giant molecular cloud. The model cluster reproduces the density profiles and structural characteristics of observed star clusters.
