Stellar Multiplicity in Open Clusters: Investigating Binary Fractions and Their Relationship with Cluster Properties

Ruan P. Alves, Hektor Monteiro, Wilton S. Dias +1

The paper analyzes binary star fractions and mass‑ratio distributions in 773 open clusters, showing that binary fractions depend on metallicity but not age, and that binaries tend…
