We present the first ever direct N-body computations of an old Milky Way globular cluster over its entire lifetime on a star-by-star basis. Using recent GPU hardware at Bonn University, we have performed a comprehensive set of N-body calculations to model the distant outer halo globular cluster Palomar 14 (Pal 14). Pal 14 is unusual in that its mean density is about 10 times smaller than that in the solar neighbourhood. Its large radius as well as its low-mass make it possible to simulate Pal… 
Mass segregation in the outer halo globular cluster Palomar 14
We present evidence for mass segregation in the outer-halo globular cluster Palomar 14, which is intuitively unexpected since its present-day two-body relaxation time significantly exceeds the Hubble
Testing lowered isothermal models with direct N-body simulations of globular clusters – II. Multimass models
Lowered isothermal models, such as the multimass Michie–King models, have been successful in describing observational data of globular clusters. In this study, we assess whether such models are able
N-body models of globular clusters: metallicities, half-light radii and mass-to-light ratios
Size differences of ≈20 per cent between red (metal-rich) and blue (metal-poor) subpopulations of globular clusters have been observed, generating an ongoing debate as to whether these originate from
Dynamical Evolution of Outer-Halo Globular Clusters
Abstract Outer-halo globular clusters show large half-light radii and flat stellar mass functions, depleted in low-mass stars. Using N-body simulations of globular clusters on eccentric orbits within
A Monte Carlo analysis of the velocity dispersion of the globular cluster Palomar 14
We present the results of a detailed analysis of the projected velocity dispersion of the globular cluster Palomar 14 performed using recent high-resolution spectroscopic data and extensive Monte
The Lifetimes of Star Clusters Born with a Top-heavy IMF
Several observational and theoretical indications suggest that the initial mass function (IMF) becomes increasingly top-heavy (i.e., overabundant in high-mass stars with mass $m > 1M_{\odot}$) with
Abundance analysis of the outer halo globular cluster Palomar 14
We determine the elemental abundances of nine red giant stars belonging to Palomar 14 (Pal 14). Pal 14 is an outer halo globular cluster (GC) at a distance of ∼70 kpc. Our abundance analysis is based
Towards an N-body model for the globular cluster M4
This paper describes an N-body model for the dynamical evolution of the nearby globular cluster M4. The initial conditions, with N = 484710 particles, were generated from a published study of this
The state of globular clusters at birth: emergence from the gas-embedded phase
In this paper, we discuss the origin of the observed correlation between cluster concentration c and present-day mass function (PDMF) slope α reported by De Marchi, Paresce & Pulone. This relation
The WAGGS project-III. Discrepant mass-to-light ratios of Galactic globular clusters at high metallicity
Observed mass-to-light ratios (M/L) of metal-rich globular clusters (GCs) disagree with theoretical predictions. This discrepancy is of fundamental importance since stellar population models provide
