Relativistic Binaries in Globular Clusters [PDF]

open access: yesLiving Reviews in Relativity, 2002
The galactic population of globular clusters are old, dense star systems, with a typical cluster containing $10^4 - 10^6$ stars. As an old population of stars, globular clusters contain many collapsed and degenerate objects.

ROTATING GLOBULAR CLUSTERS [PDF]

open access: yesThe Astrophysical Journal, 2013
Internal rotation is considered to play a major role in the dynamics of some globular clusters. However, in only few cases it has been studied by quantitative application of realistic and physically justified global models. Here we present a dynamical analysis of the photometry and three-dimensional kinematics of omega Cen, 47 Tuc, and M15, by means of

Globular cluster candidates within the Fornax Cluster: Intracluster globulars? [PDF]

open access: yesAstronomy & Astrophysics, 2003
We present the results of a search for globular clusters in the surroundings of 15 low surface brightness dwarf galaxies belonging to the Fornax Cluster, which was carried out on CCD images obtained with the C and T1 filters of the Washington photometric system.

Globular cluster ages [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
We review two new methods to determine the age of globular clusters (GCs). These two methods are more accurate than the classical isochrone fitting technique. The first method is based on the morphology of the horizontal branch and is independent of the distance modulus of the globular cluster.

Modelling Individual Globular Clusters [PDF]

open access: yesProceedings of the International Astronomical Union, 2007
AbstractAstronomers have constructed models of globular clusters for over 100 years. These models mainly fall into two categories: (i) static models, such as King's model and its variants, and (ii) evolutionary models. Most attention has been given to static models, which are used to estimate mass-to-light ratios and mass segregation, and to combine ...

Binary globular clusters

open access: yesNew Astronomy, 2000
The dynamics of a close binary system of globular clusters is considered. It is shown that the star transfer process from one of the components to the other should lead to the decrease of dimension of the first cluster with simultaneous increase of the dimension of the second cluster.
