Sizes of Galactic Globular Clusters
Abstract
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 Rh versus Rgc 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 Rh versus Rgc relationship of Galactic globular clusters.
