The fundamental straight line of galactic globular clusters

The Galactic Globular Clusters Database

The present status of Galactic Globular Clusters Database is briefly reviewed. The features implemented at the time writing are described, as well as plans for future improvements.

The Relative Ages of Galactic Globular Clusters

We present a review of the present state of knowledge regarding the relative ages of Galactic globular clusters. First, we discuss the relevant galaxy formation models and describe the detailed predictions they make with respect to the formation timescale and chemical evolution of the globular clusters. Next, the techniques used to estimate globular cluster ages are described and evaluated with...

Globular Clusters in the Galactic Bulge

A view of the Galactic bulge by means of their globular clusters is fundamental for a deep understanding of its formation and evolution. Connections between the globular cluster and field star properties in terms of kinematics, orbits, chemical abundances, and ages should shed light on different stellar population components. Based on spatial distribution and metallicity, we define a probable b...

Some Integrated Properties of Galactic Globular Clusters

On the Fundamental Plane of the Galactic Globular Cluster System

Context. The globular clusters of our Galaxy have been found to lie close to a plane in the log Re, logσ, SBe space (see Djorgovski 1995), on the continuation of the Fundamental Plane that is known to characterize the global properties of early-type galaxies. Of course, there is no apparent reason why such physically different self-gravitating systems should follow the same scaling law. Aims. W...
