000008049 520__ $$aMultiplicity among field and cluster stars is ubiquitous. Therefore, understanding the properties of binary stars is fundamental to deciphering star formation and evolutionary processes. Interactions between binary components can lead to a complex array of outcomes, including chemically peculiar stars, stripped stars, transient events, and mergers, among others. In this context, spectroscopic binaries (SBs), which probe short to intermediate orbital periods, offer crucial insights into diverse evolutionary pathways. Our presentation aims to: (i) review the history of the Ninth Catalogue of Spectroscopic Binary Orbits (SB9); (ii) present its evolution into the modern SBX database, incorporating Gaia DR3 astrometry and contextualizing with the latest Non-Single Stars catalogue from Gaia DR3, highlighting the common clean sample of 650 SBs; and (iii) explore the capabilities of the forthcoming 4MOST large multi-object spectroscopic survey, scheduled to begin scientific observations next year, with a special focus on detecting and characterizing unresolved double-lined spectroscopic binaries.
