Spectroscopic Binary Stars
Spectroscopic binary stars are double stars that
appear single in even the largest of telescopes, but
whose double-ness becomes apparent from periodic
changes in their spectra. The brighter component of
the double star Mizar (Zeta Ursa Major) was the first
star to be recognized as a spectroscopic binary.
Some spectroscopic binaries have orbits oriented to
our perspective such that they pass in front of one
another or eclipse each other. These are termed
eclipsing binaries. Algol or Beta Persei, which
undergoes eclipse every few days, was the first
known eclipsing binary. Astrometric Binaries are a
group of double stars in which the presence of the
unseen companion is determined by its gravitational
action on the motion of the visible primary, much like
Neptune was discovered through the perturbations of
Uranus. Both Sirius and Procyon are examples of
astrometric binary systems.
