Triple star systems are systems with three gravitationally connected stars, usually in a hierarchical structure with a tight binary orbited by a wider tertiary companion. Triple stars are significant laboratories for testing stellar dynamics, gravitational interaction, and complicated evolutionary histories.

Triple stars are seen with a variety of masses and locales, ranging from low-mass stars in open clusters to high-mass stars in OB associations. Observational methods involve astrometry, spectroscopy, eclipsing light curves, and interferometry, which trace orbital parameters, mass distributions, and dynamical interactions.Triple star systems are thus multifaceted and intriguing stellar configurations that shed light on stellar dynamics, interactions, and evolution. Their research provides the complex gravitational interaction among multiple stars and how such systems feed into stellar populations' diversity and unusual astrophysical phenomena.
