Such stars eventually settle down to a close binary with a distant companion, with the other star(s) previously in the system ejected into interstellar space at high velocities.
Its more distant companion, 3 Centauri B, is located 7.9 arcseconds away.
There is a third, more distant companion at an angular separation of 26.5 arcseconds that may be orbiting the pair with a period of about 64 years.
The more distant companion was estimated at 0.51 0.01" ( 77 AU) with a PA of 278 degrees.
A more distant companion, ο Cassiopeiae B, lies 33.6 arcseconds away.
It had been almost like an omen, a premonition of disaster poised to strike their distant companions, and the thought had been hard to throw off.
He dove into the newspaper and remained there all the way to the airport, except for an occasional surreptitious glance at his distant traveling companion.
Because of the dynamical instabilities mentioned earlier, triple systems are generally hierarchical: they contain a close binary pair with a more distant companion.
The binary system is orbited by a smaller, more distant companion, which has an apparent magnitude of +12.2.
Radial velocity measurements also suggest the existence of a third more distant companion in the system.
