What is a globular cluster? An observational perspective
Globular clusters are large and dense agglomerate of stars. At variance with smaller clusters
of stars, they exhibit signs of some chemical evolution. At least for this reason, they are …

Relativistic binaries in globular clusters
MJ Benacquista, JMB Downing - Living Reviews in Relativity, 2013 - Springer
Galactic globular clusters are old, dense star systems typically containing 10 4–10 6 stars.
As an old population of stars, globular clusters contain many collapsed and degenerate …

The ACS survey of Galactic globular clusters-XII. Photometric binaries along the main sequence
Context. The fraction of binary stars is an important ingredient to interpret globular cluster
dynamical evolution and their stellar population. Aims. We investigate the properties of main …

Black hole mergers and blue stragglers from hierarchical triples formed in globular clusters
Hierarchical triple-star systems are expected to form frequently via close binary–binary
encounters in the dense cores of globular clusters (GCs). In a sufficiently inclined triple …
