Los diámetros de los cúmulos globulares y sus variables

Abstract

In this theoretical investigation (which was published in 1960, Serie Circular Nº 16, La Plata Observatory) for 55 among 65 globular clusters well visible, a strictly linear relation has been found between the logarithm of the diameter of the cluster defined by is variables and the total luminosity of the cluster, in apparent scale as well as in absolute or linear scale.
