Spectroscopic Binaries With Apparent Peculiar Orbits After J. Miller Barr (1) Installed on 30 Apr 2010. Latest update 1 May 2010. Changes/modifications are in bold. This file shows a graph of computed longitudes of periastron based on a truncated version of J. Miller Barr's (1908) table of spectroscopic binaries(1). Eight Cepheid variables (which are currently considered to be pulsators) and three binaries for which the eccentricity and average orbit speed were not available, have been removed from the table. The radial lines represent the values of ω, i.e., the computed longitude of periastron, for nineteen spectroscopic binaries.   See accompanying table.
