Most Milky Way Stars Are Single - Universe Today
For many years astronomers have known that massive, bright stars are usually found to be in multiple star systems. But a recent study by Charles Lada of the Harvard-Smithsonian Center for Astrophysics suggests that most stars are actually all alone. A new study on low-mass stars - such as red dwarfs - has found that these stars rarely occur in multiples and that they are more abundant than high-mass stars, such as the Sun. Since planets form more easily around single stars, they could be more common than previously thought.
