Excerpt from Orbit of the Spectroscopic Binary Boss 6142The binary character of Boss 6142 50m.5, 6= +56° type Bp, mag. 605) was announced by Adams in the Astrophysical Journal, April, 1912. Plates taken here indicate that the H and K lines do not shift their position with the others and remain fixed. Fifty-three spectrograms have been used in determining an orbit. On seven of these the secondary spectrum was measured. There are indications of its presence on many plates where it could not be used. On those plates where the lines due to the primary and those due to the secondary are just separating, the spectral lines are very diffuse, and the spectrum is sometimes almost continuous. Where the stars are moving across the line of sight, the. Lines are fair. Table I gives a list of all those which were used in reducing the measures.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
