1201.3597 (Sidney van den Bergh)
Sidney van den Bergh
A study is made of deviations from the mean power-law relationship between
the Galactocentric distances and the half-light radii of Galactic globular
clusters. Surprisingly, deviations from the mean R_h versus R_gc relationship
do not appear to correlate with cluster luminosity, cluster metallicity, or
horizontal branch morphology. Differences in orbit shape are found to
contribute to the scatter in the R_h versus R_gc relationship of Galactic
globular clusters.
