Scientific paper
We have discovered that the nearby double-lined spectroscopic binary BY
Draconis has a proper motion companion 17 arcsec to the northeast.
Photometric measurements indicate that the companion is an M5 dwarf
lying on the main sequence. Studies of this third component could prove
valuable in determining the evolutionary state of the system.
