The structure of star clusters. III. Some simple dvriamical models
Abstract
Dynamical models of star clusters are presented, based on steady-state solutions of the Fokker-Planck equation. The models are spatially limited, corresponding to the tidal cutoff imposed by the Milky Way. Their projected density distributions are similar to those observed in open clusters, globular clusters, and elliptical galaxies. Within each model the fractional escape rate is uniform throughout. The escape rate from a cluster depends on the number of stars and the strength of the tidal force field; when expressed in this way it is almost independent of core radius or central concentration. Quantitative application to actual clusters must await a discussion of models containing a realistic stellar mixture.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
