As documented by Da Costa and Cottrell (1980), and Norris et al. (1981), the CN-rich giants in this cluster possess enhancements in nitrogen abundance by factors of 7–8 relative to the CN-poor gi

In statistical equilibrium, the distribution of stars among states of different energy, E., per unit mass would be determined to a first approximation by the probability P., where . here g. is the statistical weight of each sta

Next, these models are related to more detailed numerical calculations of gaseous models, Fokker-Planck models, N-body calculations, etc., and

Where’s the CUSP? (Or CCD Photometry of Globular Cluster Cores)part of a major study of globular cluster core structure. These data are being used to test for the presence of central cusps in the surface brightness profiles; which are expected to be present in clusters which have already undergone core collapse (Cohn and Hut 1984).

Rotational Field and Velocity Dispersion in Globular Clusters: ω Cen and 47 Tucrom the centre to the edge and the ordered to random motions ratios are deduced for two globular clusters: ω Cen and 47 Tuc. Masses through virial theorem and M/L ratios are also given. A more comprehensive study will be published in Astron. & Astrophys.
