The early evolution of star clusters in compressive and extensive tidal fields

  title={The early evolution of star clusters in compressive and extensive tidal fields},

  journal={Monthly Notices of the Royal Astronomical Society},
We present N-body simulations of star clusters that initially evolve within a strong compressive tidal field and then transition into extensive tidal fields of varying strengths. While subject to compressive tides, clusters can undergo significant heating due to two-body interactions and mass loss due to stellar evolution. When the cluster transitions into an extensive tidal field it is super-virialized, which leads to a rapid expansion and significant mass loss before the cluster reaches…

In previous papers of this series, we developed a new algorithm for modeling the formation of star clusters in galaxy formation simulations. Here we investigate how dissolution of bound star clusters

Globular cluster ejection, infall, and the host dark matter halo of the Pegasus dwarf galaxy

Recent photometric observations revealed a massive, extended (MGC ≳ 105 M⊙; Rh ∼ 14 pc) globular cluster (GC) in the central region (D3D ≲ 100 pc) of the low-mass (M* ∼ 5 × 106 M⊙) dwarf irregular

Characterization of the velocity anisotropy of accreted globular clusters

Galactic globular clusters (GCs) are believed to have formed in-situ in the Galaxy as well as in dwarf galaxies later accreted onto the Milky Way. However, to date, there is no unambiguous signature

Kinematic fingerprint of core-collapsed globular clusters

Dynamical evolution drives globular clusters toward core collapse, which strongly shapes their internal properties. Diagnostics of core collapse have so far been based on photometry only, namely on

Characteristic radii of the Milky Way globular clusters

We report on the extent of the effects of the Milky Way gravitational field in shaping the structural parameters and internal dynamics of its globular cluster population. We make use of a

Star Clusters in Evolving Galaxies

Probing dark matter with star clusters: a dark matter core in the ultra-faint dwarf Eridanus II

We present a new technique to probe the central dark matter (DM) density profile of galaxies that harnesses both the survival and observed properties of star clusters. As a first application, we

The Milky Way globular cluster system within the context of a closed box

Metallicities of the Milky Way globular cluster (GC) system are interpreted within the framework of a closed box model of chemical evolution. Model age-metallicity relations normalised to the Sun are



Evolution of star clusters in a cosmological tidal field

We present a method to couple N-body star cluster simulations to a cosmological tidal field, using the Astrophysical Multipurpose Software Environment. We apply this method to star clusters embedded

Evolution of globular clusters in the Galaxy

Globular cluster evolution is studied, modeling relaxation and energy exchange between the stars. A comprehensive survey is presented of Galactic globular cluster evolution until core collapse. Mass

The effect of secular galactic growth on the evolution of star clusters

The growth of galaxies through adiabatic accretion of dark matter is one of the main drivers of galaxy evolution. By isolating it from other processes like mergers, we analyse how it affects the

The inefficiency of satellite accretion in forming extended star clusters

ABSTRACT The distinction between globular clusters and dwarf galaxies has been progressivelyblurred by the recent discoveries of several extended star clusters, with size (20− 30pc) and luminosity

A comprehensive set of simulations studying the influence of gas expulsion on star cluster evolution

We have carried out a large set of N-body simulations studying the effect of residual-gas expulsion on the survival rate, and final properties of star clusters. We have varied the star formation

Pre-collapse evolution of galactic globular clusters

This paper is concerned with collisionless aspects of the early evolution of model star clusters. The effects of mass loss through stellar evolution and of a steady tidal field are modelled using

Formation versus destruction: the evolution of the star cluster population in galaxy mergers

Interacting galaxies are well known for their high star formation rates and rich star cluster populations, but it is also recognized that the rapidly changing tidal field can efficiently destroy

Fully Compressive Tides in Galaxy Mergers

The disruptive effect of galactic tides is a textbook example of gravitational dynamics. However, depending on the shape of the potential, tides can also become fully compressive. When that is the

Formation and dynamical evolution of multiple stellar generations in globular clusters

We study the formation and dynamical evolution of clusters with multiple stellar generations. Observational studies have found that some globular clusters host a population of second generation (SG)

The main physical ingredients driving the early and long-term evolution of globular clusters are reviewed, the possible evolutionary routes are described and how cluster structure and stellar content are affected by dynamical evolution are shown.
