spectroscopic binary definition

Binary systems deduced from effects on the spectrum are called spectroscopic binaries; they are the subject of a later module. In this way, the relation between a star's appearance ( temperature and radius) and its mass can be found, which allows for the determination of the mass of non-binaries. In some spectroscopic binaries, spectral lines from both stars are visible and the lines are alternately double and single. Many stars occur in pairs, multiple systems, or star clusters.

The term binary was first used in this context by Sir William Herschel in 1802, when he wrote: The opening line of any book should say, in the words of Stephen King, “Listen. “If you really want to hear about it, the first thing you'll probably want to know is where I was born, and what my lousy childhood was like, and how my parents were occupied and all before they had me, and all that David Copperfield kind of crap, but I don't feel like going into it, if you want to know the truth.”, The Adventures of Huckleberry Finn by Mark Twain, Dictionary.com Unabridged In star: Spectroscopic binaries. Spectroscopic binary systems are usually detected due to the movement of the emission and absorption lines in the observed spectrum, caused by the Doppler effect as the stars move in their orbit. Cf.
