CentauriSystem

CentauriSystem is a hierarchical triple-star system in the southern sky, located in the Centaurus constellation at a distance of roughly 60 light-years from Earth. It consists of three confirmed stars designated CentauriSystem A, B, and C. The primary, CentauriSystem A, is a sun-like F-type main-sequence star. CentauriSystem B is a cooler K-type companion that orbits A in a close, bound pair with an orbital period on the order of decades. CentauriSystem C is a distant M-dwarf that accompanies the AB pair on a wide orbit, with a separation of several hundred astronomical units. The configuration is hierarchical, with A and B forming the inner binary and C acting as a distant tertiary.

Observational studies have identified a circumstellar debris disk in the A–B region, indicating ongoing planetesimal activity and the potential for planet formation in this environment. Over the years, several exoplanet candidates have been reported in association with CentauriSystem, but none have been confirmed to date, and the current consensus remains that no bound planets have been definitively detected. The system is of particular interest for investigations into the dynamics of multiple-star systems and the impact of stellar companions on planet formation and orbital stability. Surveys with ground-based observatories and space missions have contributed to measurements of stellar masses, orbital parameters, and disk properties, making CentauriSystem a reference case in studies of hierarchical stellar systems.
