An eclipsing binary star is a binary star system in which the orbital plane of the two stars lies so nearly in the line of sight of the observer that the components undergo mutual eclipses. In the case where the binary is also a spectroscopic binary and the parallax of the system is known, the binary is quite valuable for stellar ...

Una binaria espectroscópica es una estrella binaria en donde las dos componentes están tan próximas entre sí, o tan alejadas de la Tierra, que no pueden ser resueltas con la vista, ni siquiera utilizando poderosos telescopios.

The catalogue of spectroscopic binary orbits (SB) is a compilation of orbital data for spectroscopic binary stars which have been produced since 1969 by Alan Henry Batten of the Dominion Astrophysical Observatory and various collaborators.
There are many binary stars whose angular separation is so small that we cannot distinguish the two components even with a large telescope – but we can detect the fact that there are two stars from their spectra. In favourable circumstances, two distinct spectra can be seen.
If a binary star is both spectroscopic and visual (by which I mean that we can see the two components separately, and we can detect the periodic changes in radial velocity from the spectra of each), then we can determine almost anything we wish about the orbits without ambiguity.
Spectroscopic binaries. Eclipsing binaries. Astrometric binaries. "Exotic" types. Visual Binaries. A visual binary is a binary system in which the component stars of the system can be individually resolved through a telescope. Long-term observations can then be made to plot the relative positions of the members of the system.
