The Alcyone star system is composed of five stars.  The two largest giants rotate around a common center of gravity, as close to each other as our Sun is to Jupiter, and no planets remain around either of them, if there ever were any.  Their fast spins have resulted in a ring of gases around them, no where near thick enough to breath, but thick enough that starships sail through the rings and refuel on their way in or out of the system.
