A recent study from the University of Madrid categorizes nearly all stars within 10 parsecs (32.6 light years) of the Sun, revealing that 215 of 424 stars are part of 92 multiple star systems. This research aids in understanding star formation and will inform future exoplanet searches.
- 01The survey identified 92 multiple star systems, including 68 binary systems, 19 triples, three quadruples, and two quintuple systems.
- 02Stars with more than half the mass of the Sun have a 41% chance of being in a multiple star system, while stars under 0.1 solar masses have only a 9% chance.
- 03Orbital periods of these systems vary significantly, from days for tightly bound pairs to tens of millions of years for widely separated stars.
- 04The study provides a vetted target list for future planet-hunting missions like NASA's Habitable Worlds Observatory and ESA's LIFE.
- 05This research is part of a series that enhances our understanding of local star dynamics and the search for habitable exoplanets.

A new study from researchers at the University of Madrid has compiled a comprehensive census of multiple star systems within 10 parsecs (32.6 light years) of the Sun. The research, which utilizes data from the European Space Agency's Gaia telescope and the Washington Double Star Catalog, identified 424 stars, 215 of which are part of 92 multiple star systems. Notably, the study found that stars greater than half the mass of the Sun have a 41% likelihood of being in a multiple star system, while those under 0.1 solar masses, like red and brown dwarfs, have only a 9% chance. This survey also examined the varying orbital periods of these systems, confirming that even widely separated stars are gravitationally bound. The findings are crucial for future exoplanet searches, as companion stars can interfere with the detection of habitable planets. The research serves as a vital resource for upcoming missions, including NASA's Habitable Worlds Observatory and ESA's LIFE, ensuring that valuable observational time is not wasted on misleading data.
