On the Problems of Classification of Globular Cluster Systems

Abstract

In this paper we discuss the problems of classification of globular cluster systems (GCS), in particular, the problem of the auxiliary parameter. The simplest methods of their classification are proposed. The possibilities of classification by the degree of concentration of GCS to the center of the galaxy and the use of the velocity anisotropy parameter are studied. Empirical relationships between the initial value of the virial parameter and the physical characteristics of GCSs are found. It is shown that GCSs can be classified using the initial value of the virial parameter.
